Mixed feelings

I saw a guy on a street corner socializing his "dog" on my way into work this morning.  The pup was wanting to run and hide as each car came by, and the guy would bring it back (it was leashed) and reassure it.  As I drove by I saw that it was a wolf pup, probably 6 months old.

My first thought was "you dickwad, wait until that twitchy animal is 120 lbs, still twitchy, and you can't control it".  My vision was of someone's 5 year old kid running by that wolf, surprising it, and the wolf removing the kids face with one bite.

That said, I'm generally opposed to people putting their noses in where they aren't involved.  So now I'm conflicted.  Is it OK for that f'n genius to raise a wolf in town or not?  My gut very much says no, its not OK, but I'm trying to reconcile that rationally.
