We might find Judas in Heaven?

We all know how Judas sold Jesus for 30 pieces of silver. The thing is he hanged himself before Jesus died on the cross so he went to (supposedly) hell. But after Jesus died on the cross he went to the underworld and preached there. Is it possible that Judas might have been redeemed there, or is it safe to presume that the only ones that Jesus preached to in the underworld were those who hadn't heard the gospel in their lifetime? What church doctrines/beliefs are there on these issues? Are they even related?
