He looks totally insane.
And while usually people eating/wiping themselves with feces, etc. and doing stuff like that before trial usually means that they are going for an insanity plea, I actually DO think that this guy is more than just a scumbag mass murderer. I do think that he is legitimately, completely criminally insane. Unlike most though, I don't see any problem in executing these people still, even if they are found to be criminally insane. That would make perfect sense for a National Socialist though, as I don't see any problem with sterilizing all insane people, retarded people, and even people that are just below a certain IQ point, I'd say about 85 or below, even if they have done nothing wrong at all. It would just make the world a better place, simple as that.
What about sociopaths. But I suppose countries aren't gonna govern themselves.
