This tells me he was regretful for what he had done. WHAT IF HE BELIEVED JUST BEFORE TAKING HIS LIFE? He will be sitting RIGHT now with Christ and the apostles in heaven according to the easy believism teaching. It's an appalling thought that Judas is sitting with Jesus and the apostles in heaven. But fortunately friends, EASY BELIEVISM is nothing but heresy. That's what it is, since it takes obedience (and baptism) out of the equation and NEGATES the teachings of the Lord.
I don't believe there is an absolutely clear answer regarding Judas. Suicide would be an odd course for someone who had just sincerely repented and believed, but perhaps not if one were overwhelmed by the gravity of having betrayed the Son of God. I've always found Judas to be somewhat of a sympathetic figure and will hold out hope until the truth is known. If he was simply created for this role - created for destruction from the get-go - I would find that somewhat appalling.
Easy believism to me is what is typically discussed here as Once Saved Always Saved. That debate is exceedingly tired and tiresome. Suffice it to say, no one in the first 1600 years of Christianity believed OSAS, the oldest branches of Christianity (Eastern Orthodox and Catholic) don't believe it in a big way, and you can support it only by doing some pretty bizarre gyrations with the Bible. More than that, whether OSAS or OSNAS is true does not affect my life in the slightest. If the OSAS sort of easy believism is true notwithstanding history and the Bible to the contrary - well, whoopee, there will be more people in heaven.
