Let's see shall we?
A patient who is certifiably insane (otherwise he wouldn't have been there in the first place) and being antagonized by (insert anyone here, male, female, color, religion, national origin, sexual preference)in the name of supposed control (when really what they were on was a sadistic power trip)ends up attempting to kill said antagonist and we are all supposed to mourn the antagonist?

The patient was insane and under what I would consider tortuous conditions does exactly what any sane person would. We were all jumping up and down and screaming Bundalo right along with him. Just like when any bad guy gets their come uppance!
