I once played D&D with a paladin who basically followed this. He was an Oath of Vengeance paladin. For the unaware, OoV paladins often have zero chill. They’re typically something akin to Batman with magic powers. My goal was to avoid that.

His oath had something along the lines of “Without the capacity for violence, pacifism is not a choice. Pacifism without choice is victimhood. I will choose pacifism whenever possible, but will not watch idly when people are victimized. I will ensure the victimized are made whole, and the victimizers know the pain they have caused.”

Basically, he would try his best to talk his way through encounters first. He would give enemies every opportunity to back down. He had incredibly high charisma to try and persuade, intimidate, or deceive others out of attacking. After all, he was attempting to choose pacifism whenever possible. But if he believed that a bully was victimizing someone, the gloves came off and he channeled all of his pent-up fury into making the bully regret their actions. And since paladins use charisma to cast their spells, his smites were painful.

The DM loved it, because it helped us avoid falling into the murderhobo trope that combat-oriented D&D players often fall into. It also gave him a chance to actually flesh out some of the NPCs who would have just been throwaway no-name combatants.
