In one culture, children being used as soldiers is moral. In another, it is not.
Rather not. For example:
I don't think children being used as soldiers is or ever was moral in Polish culture. Yet children-soldiers were used in the Warsaw Uprising of 1944.
See the analogy I made. Hardware doesn't determine the software.
And see my comment on this analogy. It is totally wrong.
If anything, while making such analogies, you should identify genes with software - not with hardware.
Nice way to completely miss the point of my analogy.
I deliberately missed the point of your analogy, because I cannot accept that this point is correct.
IMO it is totally wrong. Genes cannot be compared to hardware in this analogy. In this analogy, they can only be compared to software!
Real life example: I have two twin brothers - they're identical twins, so their DNA is the same. If the idiotic notion that genes 100% determine things like behaviour and personality, they should be psychologically indistinguishable from each other, especially since they grew up in the same environment, attended the same schools, share friends, etc. But it's not the case. They have different personalities, different interests, different ways of talking, different tastes in music, and so on and so forth.
No. You didn't fully understand of what I wrote.
That genes determine someone's behaviour doesn't mean that identic genes means identic behaviour - even under same circumstances (which is impossible because circumstances are never exactly 100% the same for two different persons).
Genes determine only a set of possible behaviour in different situations. In most of situations there are plenty - possibly thousands or millions - of possible schemes of behaviour. Genes "programm" us in such a way, that we choose from those options in every case. Of course our behaviour is directly determined by our minds. We are "homo sapiens" - we think. But our schemes of thinking - the way how we think - is determined by genes.
Thus indirectly our behaviour is also determined by genes.
I mean by "software" is the accumulated information our brain stores, accesses, and reacts upon. That's not determined by our genes, absolutely not. It's acquired throughout our lives.
Oh man... This proves that you completely missed my point.
The way our brain accumulates information, accesses & reacts upon it - the way our brain acquires information - is determined by genes!
Thus maybe even comparing genes to software is wrong.
Genes should be compared specifically to operational system - like Windows 7 - not to any random, optional software.
Software is anything we "install" during our life - and we have some influence on it (our environment, family etc. - also has).
But operational system are our genes - and we cannot change operational system. It determines what kinds of software and hardware we can install. Of course we have wide choice, as there are many types of various software & hardware compatible with our system - but this choice is limited, since not all software & hardware is compatible with our operational system (i.e. with our genes). Thus - in the end - as I already wrote, genes determine us.
But genes can't make us do specific things, like murder someone.
Completely untrue. For example psychopathy is a condition of human mind / human brain, that is largely determined by genes.
It has been proven by criminologists that genes have more significant influence on psychopathy than environmental factors (such as upbringing).
In general - not only psychopathy, but most kinds of propensities to commit crimes - are partially determined by genes.
Of course not only by genes, also for example by factors such as testosterone level during fetal life or accidents resulting in brain damage, etc.
But statistics seem to prove that genes have even bigger influence on propensity to crimes, than environmental factors (such as upbringing, family, school, etc.).
Of course the latter factors also cannot be ignored - but in general genes are responsible for higher or lower risk of becoming a criminal by a certain person. Just like genetic factors are responsible for higher or lower risk of developing cancer by a certain person. In this last case healthy or not healthy lifestyle, or proper medical care, can only dimnish or even more increase the effects of a genetical inclination of a person to develop cancer.
In a similar way proper or pathological upbringing / family can only dimnish or even more increase the risk of a person to become criminal.
There were researches conducted on 4 groups of cases of adoption (history of adopted boys was analyzed) - 1st group were children who were born in biological families with criminal past (their fathers, sometimes also grandfathers, were criminals) and adopted also by families with criminal past. The 2nd group were children born in biological families with criminal past, but they were adopted by normal families and raised by them since their infancy. The 3rd group were children born in biological families which had nothing to do with criminality, but were adopted and raised by pathological, criminal families. Finally the 4th group were children from biological families without criminal past and adopted and raised also by normal families, with no criminal past.
The results were as followed:
Percentage of sons (adopted boys) who entered into conflict with law when they grew up:
4th group - 13,5%
3rd group - 14,7%
2nd group - 20%
1st group - 24,5%
It shows that both genetical and environmental factors influence the risk of becoming criminal - but genetical factors are more important.
Another research conducted in Denmark on a statistical sample consisting of 5483 examples of adopted boys also showed that among children adopted from biological families in which fathers were criminals, percentage of boys who commited crimes when they grew up was significantly higher than among children who came from biological families with no criminal past. Among that second group percent of children who commited crimes when they grew up was only 5%, while among the group of children from biological families with criminal past it was much more.
====================================
And when it comes to twins - which you mentioned.
There is for example that story of Oskar Stohr and Jack Yufe - identical twins adopted by different families:

Despite them being adopted by different families, their "CVs" are pretty similar.
