Excuse me, but who in the hell are you to judge what does and doesn't make it a Champion? You were going to sit idly back while the entire town was destroyed. I'm all for free will, but there comes a time when one person cannot stand between the salvation or damnation of a group anymore.
Peter had every right to take your blood from you, and it's not like he didn't give you a chance to change your mind. He hardly wanted to do it.
So do yourself a favor and stop playing the role of victim already. Nobody cares about your whining about civil liberties when the lives of their friends and loved ones hung in the balance.
