I think it's highly possible Tengan didn't mean everyone was the attacker, but rather had committed atrocities in the past. Even Asahina, who planned to murder everyone else after Sakura died, and Naegi, possible something in the past.

As for the real attacker, it was most likely Kyoko. The evidence stacks up against her, especially Asahina holding up the notebook. Who was the last person of the final killing game to die? Kyoko. That explains the inconsistency of her laying position before and after she died. And it's possible she went and killed Ruruka in the time everyone was out. That explains Asahina saying "The killings are over." When she and Ryota came to help Naegi.
