How does it help this young man to be imprisoned, when that means that it will impact on his ability to find employment for the rest of his life, and that in turn impacts on whatever family he will have in the future. The judicial system, instead of looking at him as a criminal, can see him as someone in need of a behavior adjustment and help that by making him work with animals.

Nothing changes hearts and minds by having to interact with the people/issues that you have no regard for.
