So the first answer why is Evill allowed to exist is that in the grand scheme of things that Evil exists so that the greater good can be achieved. An unconventional answer for sure that creates another problem. If Greater good is the most important can Human sin so that he can achieve a greater good ?
Is he then sinning ?
Well, some theologians and philosophers alike would argue that the goodness or otherwise of an act lies in its consequences. On this view, if you do something normally considered wrong because you know that its good consequences will outweigh its bad ones, then it is a good act. So if a thug asks me where my friend is hiding so he can kill him, and I lie to him, that is a good act and I have not sinned. Many Christians have argued along these lines. But many others have not, and have insisted that such an act would indeed be wrong no matter how good its consequences seem: the end cannot justify the means. Kant famously gave this answer when the example of the thug and the friend was put to him. The Catholic Church teaches that consequentialism is mistaken and that certain acts are always sins, even if they might seem to bring about better consequences.
Now the traditional Christian view about sinful acts is that the sin lies in the intention rather than the action; if I intend to do what is right but accidentally commit a sin then I haven't really sinned, and if I intend to sin but somehow fail to do it, then I have indeed sinned. This is the view of Augustine. On these grounds one might argue that a sin committed in order to prevent a greater sin isn't really a sin, but I think the church has generally avoided such an argument.
In the context of predestination, it's important to recognise that one cannot know what God has planned. For example, right now I am considering whether to sin or not. I know that whichever choice I make, it will be the one that God has predestined for me (on the assumption that predestination is true). So I know that if I sin, it will be what God wants, but if I don't sin, that will also be what God wants. The problem is that right now I don't know which. So it is still my moral duty to try to avoid the sin. I can't say that God wants me to sin, therefore I should do it, because I don't know that that
is what he wants. Of course, if I then commit the sin, I will know that I was right and it was what God wanted. But that doesn't change the fact that, at the time, I did not know this, and so I was not committing the sin in order to achieve whatever greater good God might bring out of it; I was committing the sin simply because I wanted to. If I really cared about God's plan I would have avoided the sin, because I would know that even though God can bring greater good out of sin, it is better to have no sin at all.
Then there is another similar problem that i kind of pointed in the second post. If every action done by humans is predestined and results to a greater good then no action a human can take can be characterized as evil. There are no morals. Everything is the same and good because is the will of God. So when the answer to why Evil exists is that there in the grand scheme of things there is no Evil anything is according to plan , then the theological position of human salvation by helping them self , by showing remorse and bettering oneself becomes useless. That is the problem of a theory that supports Moral relativism with a twist. As everything Evil is done for the good.
Not necessarily, because we can distinguish between intrinsic and extrinsic desirability. Say that sin X brings about greater good Y. If we know the whole situation, we can say that X is desirable, but it is desirable only because it brings about Y; it has "extrinsic desirability". If we look at X alone, without considering its role in bringing about Y, then it is undesirable. So it has extrinsic desirability but intrinsic undesirability. This ties in with what I suggested above: we don't know the whole context, because we cannot see all the effects of our choices. All we can be certain of is the intrinsic undesirability of sinful choices. When I am faced with the choice whether to sin or not, I can't know whether, from God's perspective, the sin has extrinsic desirability, because I don't know what all of its effects will be; I can't know if the good effects (if any) will outweight its intrinsic undesirability as a sin. All I can know is that intrinsic undesirability, which is why it is my duty not to do it, irrespective of whatever extrinsic desirability it might have. So in this way one can distinguish between right and wrong acts even when accepting that some - perhaps many - wrong acts are ultimately right because of their consequences.
If the existing world is the best possible then there are some serious question regarding the theological principle of sin. Apparently the world is an evil place because all humans are sinfull more or less and they should try to improve thereselfs. But if the world is the best there is then that would be impossible.
When I said "the world", I meant the whole thing in time as well as space: the whole history of the universe. To say that the actual world is the best possible is to say that the sum total of everything that happens is preferable to any other possible sum total that might have happened instead. It doesn't mean saying that the world
as it is at this precise moment is as good as it could possibly be. In fact one might plausibly hold that this is the best possible world while also believing that the world is in a sorry state at the moment; one might also believe that it will get far better in the future, and it is this vast amount of future happiness which outweighs the current misery. Note that I'm not suggesting that happiness in heaven outweighs misery on earth, but that earth itself might get better - which is of course the traditional Christian view, at least if one believes in a future thousand-year reign of Christ on earth.
On a non theological context without the idea of sin it also doesn't make sense. As long as there are moral systems which may or may not be based on religion then the world is not the best it can be.
I do think that all of our thoughts and actions are greatly influence by our animal nature. The same way Humans are hard coded to show emotions around sex , they also have impulses about being selfish and act in evil ways. In a very distorted sense the argument that all humans are born sinners is actually truth. However it is very simple to imagine that there could be created Humans that weren't programmed to act in such Evil ways . Though as people we can be less Evil than each other then a world can in respect be more perfect. Which is also an idea that is found in Religions which generally claim a moral code while that position claims Moral relativism.
In the computer age Human imagination has captured how such things can be possible. That is by creating a being that's it's nature prohibits it from being Evil. That doesn't mean it won't understand it. It just wouldn't want to do it in the similar way that a human may not want to do extreme good. Asimov's third laws of Robotics if put to practice could create such a character but it's future is either to become Evil or Slave of Humanity.
Right, and personally I think such a situation would be preferable, which is why I think that the actual world is
not the best possible. Now Leibniz argued like this:
(1) If God exists, then the actual world is the best possible.
(2) God exists.
(3) Therefore, the actual world is the best possible.
I'd be inclined to accept his premise (1), but turn it around like this:
(1') If God exists, then the actual world is the best possible.
(2') The actual world is not the best possible.
(3') Therefore, God does not exist.
Of course I don't think that my (2') is really proveable, any more than Leibniz' (2) is (although he thought God's existence could be proven), so this is hardly a knock-down argument for atheism.
Many people would argue that creatures following Asimov's laws of robots would not really be proper moral agents - a creature that doesn't have the option of doing evil cannot meaningfully be said to do good. And a world that contains genuine moral agents is intrinsically preferable to one that doesn't. So to create the best world, God has to create us with all our capacity for evil. Personally I don't buy into this argument, but I suppose really it's a matter of taste.
Well since Gregory argues on what happens on this world i would just ignore altogether the after life implications. Gregory argues that always when Evil happens it is so that a Greater good may happen .
Large parenthesis of logic on a topic having to do with theology
Logically i find his argument to be the best argument against predetermination being a result of a good being which controls it.
For example if your spouse dies because of cancer that means that she would have acted in ways that would cause great misery and it was for the best . But she may have shown signs that she would never act in such ways due to being kind or for example not having any intelligence to be evil. And when whole populations where taking the biggest hits from the plauge i can't see how that had any positive sideeffects.
The wife wouldn't necessarily have had evil intentions. Perhaps she would have done something quite accidentally that happened to have terrible consequences; perhaps she would have had a baby that would grow up to be the next Hitler. Of course that raises the question: why, then, did God not kill Hitler's parents before they had him? It's hard to imagine how there could be anyone much worse whose parents had to die when his were allowed to live. But then, for all we know, the world would have been much worse if Hitler hadn't lived; perhaps in his absence the Nazis would have been led by someone more competent who would have won, as in Stephen Fry's
Making history. Someone who is committed to the belief that this is the best of all possible worlds would have to argue that this is true. Of course there is no way of showing that it's not true.
The existence of big disasters claiming lots of lives is of course a traditional argument against this sort of theodicy. The classic example was the Lisbon earthquake of 1755, which killed many thousands of people right as philosophers were insisting that this is the best possible world. Voltaire wrote a famous poem attacking Leibniz and his disciple Wolff on these grounds (they couldn't answer back, because they were both dead):
Voltaire said:
Come, ye philosophers, who cry, “All’s well,”
And contemplate this ruin of a world.
Behold these shreds and cinders of your race,
This child and mother heaped in common wreck,
These scattered limbs beneath the marble shafts –
A hundred thousand whom the earth devours,
Who, torn and bloody, palpitating yet,
Entombed beneath their hospitable roofs,
In racking torment end their stricken lives.
To those expiring murmurs of distress,
To that appalling spectacle of woe,
Will ye reply: “You do but illustrate
The Iron laws that chain the will of God”?
Say ye, o’er that yet quivering mass of flesh:
“God is avenged: the wage of sin is death”?...
Think ye this universe had been the worse
Without this hellish gulf in Portugal?
Are ye so sure the great eternal cause,
That knows all things, and for itself creates,
Could not have placed us in this dreary clime
Without volcanoes seething ’neath our feet?
Set you this limit to the power supreme?
Would you forbid it use its clemency?
Are not the means of the great artisan
Unlimited for shaping his designs?
If Leibniz had still been around, he would have said that in itself, the earthquake couldn't be proved to have been ultimately a good thing - after all, all the evidence would point to its being overall a bad thing (what good could come from it that would outweigh all that suffering?). But his argument that this is the best of all possible worlds was not based upon an examination of the evidence in the world, it was based upon the argument I gave above. If God can be proven to exist, and if the principle that God always does the best is accepted, then, he thought, this
must be the best possible world, no matter what evidence appears to the contrary. When faced with events such as the earthquake we must simply bear in mind how little we really understand of how the universe works or what is going on elsewhere in its vastness.
