Judas died before the Church was born.
"Judas died before the Church was born."
That is questionable, depending on when you think the Church began. If you consider the Church the people of God, it then started with Abraham, I suppose. Some refer to Pentacost, others refer to naming Peter as the rock. The question originally asked, "Is Judas in heaven", has no bearing on when the Church began (Didn't Christ descend into "hell" to bring the OT people into heaven?). Only God Himself can judge whether Judas repented or willingly entered into some mortal sin. Suicide is not necessarily a mortal sin that separates us from God. It depends on the person's inner relationship with God. Only God can judge that. That is why Catholics do not teach (shouldn't!) that Judas specifically is in hell.
