"I want to kill people" isn't a "political view" in the sense you seem to imagine. Maybe I should have emphasised the bit where he wants to kill people more than the fact he's a Nazi? But the two are intertwined. He wants to kill people because he's a Nazi, these are not unrelated in his mind.

I'm sure in his mind it makes sense. But everybody else disagrees and considers that, as you said, the murderous lunatic can't be released.
