Hmm...thief would have to be less like a Final Fantasy thief and more like Ishikawa Goemon or Nezumi Kozo. I have no problem with Thief being reimagined as a class that leads to the ninja job. Don't know how others would take that, though.

We need 'hate' control
No, we don't. This was a dumb gimmick that, along with Treasure Hunter, kept THF down and stunted its growth.
