I'm the Villain

Villains, even dogs... (The system lights up the red light of death.) Dang! Become a villain! It makes the protagonist suffer, it makes the protagonist suffer, and it makes the protagonist feel wronged. Without my presence, how can the protagonist grow step by step? One torture lasts an entire episode, but it's just the last few minutes of suffering. He was just stabbed to death by the protagonist. Me, I am the tool of the strongest villain (eight duck meat, woo woo woo).
