Judas was told he will inherit eternal life at one point.
Matthew 19:25-30
25When the disciples heard this, they were greatly astonished and asked, “Who then can be saved?”
26Jesus looked at
them and said, “With man this is impossible, but with God all things are possible.”
27Peter answered him, “
We have left everything to follow you! What then will there be for
us?”
28Jesus said to
them, “Truly I tell you, at the renewal of all things, when the Son of Man sits on his glorious throne,
you who have followed me will also sit on twelve thrones, judging the twelve tribes of Israel.
29And everyone who has left houses or brothers or sisters or father or mother or wife or children or fields for my sake will receive a hundred times as much and
will inherit eternal life.
30But many who are first will be last, and many who are last will be first.
