Indeed, with the way events turned out it is a compliment that people feel so strongly about Perfect. And the hilarious part of it all is that I don't think the characters would be achieving much, even if they did kill him; once he realized that he would reawaken after every death, becoming a little closer to being a true monster with every death, chances are that he would no longer fear death at all.

...What have I done? I have created a monster!
...Excellent.
