So, on one hand, Judas is helping Jesus meet his destiny by betraying him. Even if God is going to use it for good, that doesn't make the betrayal a good thing. Even though Judas' betrayal led to Jesus death and then to the resurrection and salvation for all who believe, it was still not a good thing. I think that in our day and age we desperately need to call sin, sin. We need to say some things are wrong.
Sexual immorality is wrong.
Fornication and adultery are always on lists of evils we need to avoid. Drunkenness is wrong. Even if such sins make you feel good. Even if no one gets hurt. Even if some good might come of it.
