Sam, how many people has Sylar killed since he got on board? And despite whatever stupid, lying claims he might make about how much he's changed, do you think he has ever intended to stop?

Do you think he wouldn't kill me if his warden would let him get away with it?

Do you think he would have had a remarkable change of heart about trying to convince me to kill myself, last time I spoke to him?

Comrade, I do not think that you will be able to find a convincing argument for this not being a good thing.
