Some people think, when Jesus foretells Judas' betrayal, it was actually a command, which Judas followed of his own free will and loyalty, even though it would make him look very bad. https://www.bibleserver.com/ESV/John13:26

By giving the command Jesus could be arrested in a controlled situation on his own terms without much collateral damage, as he knew he had respawn powers, which he vaguely foretold as well.

Some Christians also believe that Judas dying before Jesus resurrection means he might have been freed from hell as part of the Descensus Christi ad Inferos aka the Harrowing of Hell.
