Maybe he would be a disaster for the world, maybe he wouldn't. Nobody can say for sure.

What I absolutely do know however is;

  • If it weren't for him, I would be dead.
  • If it weren't for him, all my companions would be dead.
  • If it weren't for him, the entire world would definitely be dead.

All he wants afterwards is remake the Knights Of The Shield. It's the reason why Gortash even found him to begin with, so surely it wasn't a bad thing for the city considering how it prospered under his influence. But regardless of what drives him, his actions saved the world and ensured I have a future afterwards.
