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

There is a Gospel of Judas that the church won't include in the Bible because they say it's heretical.

It's worth reading. but it doesn't fit the Catholic narrative. It's the same group that used the Gospel of Mary.

"In contrast to the canonical gospels, which paint Judas as a betrayer who delivered Jesus to the authorities for crucifixion in exchange for money, the Gospel of Judas portrays Judas's actions as done in obedience to instructions given to him by Jesus of Nazareth. It does not claim that the other disciples knew about Jesus's true teachings. On the contrary, it asserts that they had not learned the true Gospel, which Jesus taught only to Judas Iscariot, the sole follower belonging to the "holy generation" among the disciples."
