Who's the real monster? Urgot or Warwick?

Urgot and Warwick. Both these champions struggle with retaining their humanity, but which one has become the real monster?

Warwick was transformed into an animal who is always angry and goes into a murder frenzy whenever he smells blood or gets hurt. However, he tries to mainly hunt criminals, showing at least some humanity via a wish to not harm the innocent. On the other hand, he has no control over who he kills once he goes into a blood frenzy.

Urgot is the mind killer. He's ugly, horrifying and mentally twisted. He's a mishmash of dead flesh and machine; visually, he's the stuff of nightmares. Every moment of his undeath is excruciating and filled with hate for everyone and everything. The only thing that drives him is revenge. He doesn't kill because he finds it fun or cause he needs to, but because he's angry at the world.
