Yes, but that fact that you are aware of the wrong and right and the law is not the result of free will. It's only your brain and life experience. It just couldn't have happened otherwise. That doesn't make you neither culpable nor virtuous (not the right word but I hope you get the idea).
Your more recent posts were interesting, and I kinda got a better understanding of the point you are making.
You're right in so far as my lack of ignorance of the law, etc are the result of my life experience, and it doesn't make me either morally superior, nor morally inferior.
For me, unlike some who have posted in here, I am not a determinist. I think from a practical point of view, even if ultimately it's not technically correct, we should allow for the concept of free will in our thoughts, and in our decisions. I can go into that in much more detail, but it would probably be a sidetrack.
In terms of moral responsibility, all people on earth have morals, in my opinion. Their history forms these, although I honestly believe there is an element of self-direction as well. But regardless, they then need to determine their actions in relation to these moral beliefs. There is no single objective morality to measure people against, and taking the appropriate 'moral' action is commonly measuring various moral beliefs against each other.
For example, caring for my child versus not stealing.
So, to your ISIS example. Socially, they're responsible for their actions. Morally...meh...their morals are their own, and buggered if I could make sense of them. It is why, though, I am a firm believer in sharing of ideas freely. The social model they are locked into inhibits learning and development. Their morals are skewed (sure, that's a value judgement, and not objective, I readily admit) and the mechanisms for improving that moral view are retarded. So perhaps they're not morally responsible. At the end of the day that would actually make little difference to the nature of their crimes in my head.
What it might impact is how best to disarm them.
