Morality is probably best left to analyzing intentions and not actions or things become nonsensical. Our courts don't put a paranoid schizphrenic to death because it's unclear whether his actions constitute "murder" or.... what? for all we know, he was killing bugs bunny yet again because the hairy bastard just won't leave him alone. It's impossible to judge a mind if you can't even get the smallest grasp on how that mind perceives the world.
I'm going with intention. While actions can be taken at face value and are therefore much easier to process, they can very often be taken incorrectly, too. Intentions should drive actions, but the same intention can drive different individuals to different actions. Moreover, the same action can have different meanings to each the recipients or observers of that action.
Actions alone are just too shallow of a judgement.
