Why did Jesus betray Judas? chose him as a disciple then used him to betray him for his own interest? ?

.Now that is interesting. As in Islam Christianity predestines some peoples future.And that is totally immoral. Especially if that future is Hell.Christians love to rant on about "free will" but there are eight different verses where God "hardens the heart" of the Faraoh so that he would not let the Jews leave Egypt. Its all so silly. Would Judas dare betray Jesus of his own free will knowing this would result in eternal hell for him.
