Sounds workable, except for the ones that are lured to him, but that is probably rare.
A lot of them seem to have a brilliant sociopathic capacity to lure; set traps; just appear; stalk--whatever it takes to get their sick 'jollies.'
That's one of the reasons I think something creative needs to be done--and the most sensible to me is the group home/farm thing with some suitable work and strict boundaries.
