@Shinji: WTF are you smoking? Since when does Shinn like killing? He does it to protect and save stuff, he isn't a fucking bloodthirsty nutcase.

I still say many of you let your hatred for Shinn cloud your judgement over what's happening in the show.
Shinn is a mental case, it's as simple as that... He thinks that by killing all "enemies" he will be doing the right thing toward his family (or himself in avenging them or something as stupid as that). He does feel better by killing his enemy because it sooths the pain of the ones he loved that died... It is common sence that people feel better when they are avenged. Shinn has just taken this to a totally different level by blaming everyone that steps on his toes and everyone that is an opposing party to what army he is fighting with...

I would not want Shinn to join Kira and AA because he is such a mental case that he would destroy everything they are working for by going berserk every time he step out on the field of battle.
