The worst part is that the assassin is most likely more retarded than evil.
His deed is evil af, don't get me wrong, but the killer himself is very likely retarded to the point of self-identifying as good while doing objective, undeniable evil.
He probably thinks he's helping saving the world from fascism (bit late).
Literally stormtroopers who self-identify as Jedi Knights.
