Onto a darker perversion - a friend of a friend was recently arrested on the south island for making sexual advances to a 13-year old. He may be charged with some similar offences also. Apparently this person has already been to jail for one such offence.
I mostly feel sad for all concerned. As to whether it would effect my friendship with the accused, well, we don't really have a friendship anyway. I was his acquaintance for a while until he started to bully me in subtle yet nasty way - I retreated immediately from the acquaintanceship. Since then, I have discovered my opinion of him has overlapped with many in the friendship circle.
Although ultimately I like to judge people by how they treat me, I am also wary of those who mistreat others - lack of respect is a behavioural pattern rarely restricted to only one behaviour.
