Well, there we have it.
Rehabilitation of a juvenile is not allowed or possible; nor is the possibility that a 16yr old girl would be able to determine her own attitude and opinions. Personally I believe that the general consensus would be that, as long as he has subscribed to reasonable behavioural guidelines of his probation, then he should be allowed to develop within a reasonable and thinking society. Save your hate for them that really deserve it (he may eventually), indeed, build the gallows and swing'em and all of those who will grow into your expectations.
When my boy was 15/16yrs old I thought of him as a bairn and I strove to be his moral compass, as I did his sisters, but he saw and judged things for what they are (they call it growing up and becoming a person of individuality); hopefully, 16yrs later it has worked out. Many have used the term, child; I don't know what that means to you or where you draw the line, but children are influenced by many things and react in all manner of ways - judge and be thoughtful of how easy it is to groom and corrupt a child - bragging about microdots at 13yrs old springs to mind; is that good and clever? The ones that want it deserve us movers and shakers, of such high moral and liberal opinion, to offer them an option other than the devil or his acolytes; that includes some level of forgiveness and tolerance by reasoned judgment.
This guy might just be a total knob of the worst order, but how many of you, in your halls of judgment really know what he is now?
