If you can use your brain to tell logical right from wrong, and understand the rules society has put in place to treat each other humanely and ultimately survive as a species, whether you agree with them or not, whether you can feel remorse or not, then yes, I believe you are responsible for your actions, lesions or trauma and all.


If you know stealing or killing is bad, wrong, illegal or whatever, and you choose to proceed anyway because it makes no difference to you (no remorse, no conscience) then you are still responsible for your actions.


Just because something can be explained does not mean it should be excused.
