A few things, actually. First off, I considered trying to kill him with the same method use made me kill others with, but I wasn't powerful enough when I had the chance. Now he knows enough to certainly have some form of protection against me.

Second, I had a plan, that would have come to fruition in a couple of months. He'd be at the center of public attention, everyone would have seen a public announcement about his true behavior, and he would have lost everything at the moment he thought he was secure. I would have been killed, yes, but I could accept that if I dragged him down with me.

Third, I didn't kill to escape. I killed to keep my secret from getting out early...and to keep Akira's secret. What he's hiding is something Shido would have him killed for, too. ...Something he already ordered me to kill him for, actually, but the secret being publicly announced would make it possible for him to do that without me.

Fourth...I pushed them in the right direction. I called for that review of the evidence, knowing the fabricator's interference was keeping them away from my trail. Because you're right, I am an amateur. But I'm not exactly torn up about not having the guts to kill ten people in one fell swoop, just to save my own pathetic life.
