yeah, thats kinda not good. i didn't know what the guy did, i saw a couple of scenes where he tried to plead insanity to get out of his responsibillity. thank you for bringing this up.
I don't know how it is in the USA but here pleading insanity is not a way to "get out of your responsibility", it can actually be a risky move because you are at risk of being imprisoned for the rest of your life. While a normal life sentence normally isn't a life sentence.
