Sometime it's possible for me to at least understand the rationalization they must be going through (e.g. "stealing from rich people is okay they still have plenty, while I have nothing and was born poor", "Not cool but they will get past it and maybe I'm doing them a favor teaching them a life lesson, look at that security if it's not me it will be someone else", ...). It's both reassuring because it shows that in the majority of the time people still have a conscience, and frightening because sometimes there are no rationalization possible and it's purely a sociopathic/evil enterprise.
