I tried clearing out a fort once because I wanted to see what was inside. A few dozen killed men later and I realized that they wouldn't stop spawning. Furthermore, my honor meter was as low as it could possibly be. I was basically Satan at this point.
Went to nearest town, said hi to a few pedestrians and noticed that my honor went up slightly.
Brilliant idea incoming.
I rode to Saint Denis and greeted every person I saw until Arthur was considered a saint.
Wonderful.
