I don’t consider molesting multiple sisters a mistake. Its not hate to hold Christians accountable when they err. Yes God forgives one of sin that doesn’t mean one escapes paying a price for that sin.
He was held accountable, though. What do you want done to him now? What price do you want him to pay?
You say "Molesting" as if to imply intercourse, but my understanding is that he touched them while they were asleep. Yes, that's bad, but it is not in the same league as Lenna Dunham repeatedly diddling around with her little sister.
