Sex offenders are more likely to repeat the crime probably more so than any other crime. If I were a parent I would want to know exactly who they are and if they live next to me. Unfortunately, for them, this is the consequence of raping little kids. If you don’t want your name on the sex offender list then don’t commit the crime. I have no sympathy for this at all.
As a Christian the Lord calls us to forgive the person not necessarily to trust the person.
