There is no purgatory.
But, have no fear, for the Lord stated that vengeance is His. He will deal with the wrong doers in His way, in His time.
As for us, whom of us knows....maybe, this man is truly repentant. If you read the article, it stated he has a brain tumor, and maybe that was impairing his thinking and was feeding his drinking addiction. He says he's a changed man. I wish to believe so....however, I know that while I can be fooled, nobody will ever fool the Lord.
Lord, have mercy on all involved, and ease everyone's pain.
