I don't like the man, I don't think he's a redeemable person in the eyes of the ex-JW community.
Actually, one of the main reason many of us have left is the lack of forgiveness in the JW cult. You commit a sin? We might disfellowship you and will keep record of it in a file that will follow you from one congregation to the next. This is the furthest from being christian.
If we claim someone "not redeemable", than we are no better then they are. That being said, it doesn't mean we'd need to become friends with the guy and assume he is magically a good person if he ever chose to leave the JW. All I'm saying is that we'd need to give the guy a chance at redemption. Who knows?
