Why isn't Judas considered the greatest hero in Christianity?

The very name Judas is synonymous with betrayal.

But if you believe the events of the Bible, here's a dude who was one of the chosen 12 who gave up everything to follow Jesus. They were a brotherhood. And then this event transpired that had to happen for the salvation of the Earth. In fact, Jesus asked that the cup be taken away, and God said no. That ish was going down.

So in comes Judas. Dude has to betray his friend and teacher because God is making it happen. So this pawn gets carried along in the tides of prophesy despite clearly not wanting to. And it damages him so much he kills himself and donates the money.

And somehow HE'S the bad guy. Dude is the definition of a hero. Sacrifices his own desires for the greater good.

(apparently there some apocrypha that suggest he was a good dude.)

And I did a search to make sure this topic hasn't been covered, but there was so much Judas priest to sift through I gave up, so sorry if repost.
