*Kills all the soldiers fine but spares the evil noble lord even though they've murdered countless soldiers meaning they can't get in the people's good books.*
Innocent people trained and paid to guard a noble they hate and just need the money? Nah, they can die. Evil fucking noble that rapes people and thinks he can get away with anything he likes? Ok, he can be spared.
Like... If you're gonna start sparing people, then do it from the beginning.
