If you want your problems to be solved with brutal catharsis, then your hero should be someone who believes in brutal catharsis.

They don't have to begin there. This can be something they come around to over the course of the story, as they grow and change per their character arc. But by the time of their ultimate encounter with the villain, their values should be the values that drive the story forward.

There's this thing in D&D that some DMs do. Where, when you roll enough damage to deplete the monster's hit points, they'll turn to you and say, "That's a kill. Describe for the group how you take the monster down." And you're allowed to come up with some cool maneuver or something that your character did in order to deliver the finishing blow.

The hero's ultimate triumph over the villain is a lot like this. More than any other part of the story, this moment is their apotheosis. It should be a celebration of everything they are and everything they stand for.
