Actually, “Being a Catholic I would have to say that his soul is still stained. Unless he receives absolution from priest he still in in danger of eternal damnation.” is NOT Catholic.
First off, we have no place to say that someone’s soul is still stained. We have no idea, particularly when someone has expressed regret, if not repentance.
Second, the forgiveness of sins requires contrition, either perfect (love of God) or imperfect (fear of punishment). So, if a Catholic confessed his sins to a priest, but was did not have contrition, there is no absolution. A valid confession also requires a firm purpose of amendment, i.e. the intention to not sin again.
Sounds like this guy has some bad religious education... You didn’t teach him before you left the Church, did you.

I can't quite wrap my mind around these two different concepts generating forgiveness.
