Without going into specifics, it really depends. I don’t know the details of Den Watts’ case, but if he’s done his time for a single crime, acknowledged his actions, perhaps had mitigating circumstances of some kind, recognises the harm he’s done, showed remorse and since proven himself to be a relatively upstanding person then yes, there may well be scope for not writing him off wholesale. In many of these abuse or harassment cases, I very much don’t think so though - few people seem to have changed their attitudes, shown any remorse or understanding of what they’ve done, and often acted over a prolonged period of time.
I suspect I would be more likely to allow a second chance to a reformed sexist or racist with changed views than someone who physically acted in a harmful way though. Mind you, can we ever really know whether someone has changed or if they’re just pulling the wool over our eyes for acceptance though?
Slight stream of consciousness rambling there, so I may have missed the mark somewhat.
