My guess, Drive Knight is the mad cyborg, but snapped out of it, or maybe still is evil, but prioritizes revenge. And he propably didn't even lie, the mad cyborg, himself, destroyed his village too. I also think Boyfoy is a red herring, he most likely is machinelike and immoral, but not outright evil world conqueror.
Then again the obvious being the obvious might be an amusing subversion, when everyone expects that things aren't as clear than they appear to be.
