Judas

Luke 22:3 - Then Satan entered Judas, called Iscariot, one of the Twelve.

I wonder if Judas knew that a devil -- Satan himself, no less -- had entered into him. In other cases of demon possession, the possessed usually acted in very strange ways. We don't hear of anything so strange with Judas. Yet he still may have known there was something different and evil inside that hadn't been there before.

I wonder if Satan remained in Judas until his death or if he left before that point. Perhaps he only stayed until the capture of Jesus. Then again, that wasn't very long before Judas hanged himself.
