I think everybody who has read "Mein Kampf" could tell that old Adolf was a serious nut case...
But being a nutcase isn't enough of a reason for getting killed. The question is: did we have any reason to believe Hitler was eventually going to form a government when he wrote Mein Kampf? It seems unreal. But the fact that he got enough support from ordinary Germans brings us back to MobBoss' point: in all likelihood, if you kill him, somebody else takes his place and is just as popular, and history doesn't change that much.
Look at sharpe's link or for something even better known, the KKK. Does anyone actually believe that these "people" will ever be in control? Of course not. But if they do end up in a position of power and start doing the crazy things they'd be likely to do, our descendents will ask: why did we just not kill them right there and then? Couldn't we see they were maniacs? Answer: it's clear they are maniacs, but we just can't imagine a situation in which they are able to do something of the magnitude of what Hitler or Stalin did. So would killing the Grand Dragon (or Great Wizard, or whatever these idiots call their leaders) benefit the species? I happen to think we are better off without their irk. No doubt about that. But maybe the murder brings about publicity or good will or any thing that lead them back to some sort of preminence. Next thing you know they run for office and become a viable third party.
I think MobBoss' point is that you don't know ahead of time if doing the deed might not actually worsen the situation. My point is that not only is this true, but if you decide to keep track and kill every nut job in existence, you are also going to kill a **** load of people who would never have gotten the "chance" to put their craziness in practice. So you need to decide ahead of time which ones are the most-likely-to-be-remembered by our descendants. And that we don't have a way to do so.
At any rate, we cannot go back and kill Hitler and Stalin. So the best we can hope for is that we have learned from our past mistakes, and that Hitler- or Stalin-types don't get a chance to lead.
Personally, I think the West will see a Hitler-type again within 100 years, but we will only be able to identify him once it's too late.
