NO, FUCK THAT.
Break the neck of that fucking turd, proving to him that he is wrong; if the weak must obey the strong, then break every single bone in his body, paralyze them from the meck down, proving that you have utter and complete dominance, and make them ADMIT that you have dominance, even if you have to snap their neck and heal them multiple times... and then tell them they're WRONG about the need to kill everything they love and care about just to "BeEs StRoNk derr hur hur..."
Don't leave that piece of shit alive while they think they're correct.
