Hope this doesn't cop out by making the bad guys "relatable" down the line. I hate that gimmick. Proper revenge stories should be like ad-blockers. Kill everything. None of that "acceptable ads" bullshit.
That's good and all, boy, but you're just one person. Eventually, you'll be subjugated if it's just you and you don't do stuff covertly. Then you won't get your revenge.
