Ah well, I'm just gonna post that Sayaka tries to heal him but fail because she can't resurrect dead people.

 He's not technically dead. Just corrupted. He might corrupt the others, if he stays long enough. If they attracted to Lust. Anger. Tricking People. Anarchy. Greed. So if your not a saint or the pope,  you need to deal with him quickly
