Why was this man villainized to such an absurd degree? Because he helped an old war buddy he felt indebted to fuck with the kid who ruined his business over thirty years ago? Everyone else gets redemption arcs and becomes BFFs with Danny boy, but Terry is treated as the devil, and somehow worse than the guy who kept bringing him into all the shit. Running a successful, growing business which teaches kids to not be pussies doesn't make him a supervillain. He may have done some questionable things, but that was only in response to Daniel relentlessly targeting him and not resting until he destroyed his life.
