@Yuki - No one ever tried to remove blame from the girls, since it was quite obvious that everyone was at fault to some extent in the whole story. BUT, what a certain someone was trying to show was that Itou was the victim, or deserves less blame than the girls (particularly Sekai) which I believe is plain idiotic.

@Ryll - I dont think Sekai is as devious as you made her seem. She may have done those things with such an intent, but such an intent would probably be subconscious (she wasnt aware herself, at least completely) and caused by her desire to get close to Makoto rather than a premeditated deception.
