It's interesting that this quote from Jesus, speaking in John's gospel, has come up several times on this thread. The story (in John chapter 8) is of the religious people who were trying to trap Jesus into permitting them to carry out capital punishment against Roman law. They were asking if they could stone a woman who had been caught in the act of adultery. In other words this woman was just a pawn in their attempt to catch out Jesus.
In the case before us here there is a woman also who has not been very prominent in our discussions. According to law she is the victim here. She might also be portrayed as a pawn. But surely any rehabilitation of an offender has to give at least equal if not more consideration to the victim herself. What would we be saying to her and to other vulnerable women if we were to give this person "a second chance"?
I do not express a public opinion. But I simply point you to the Scripture.
