Ah yes, music is so crucial in helping set the mental tone while writing/drawing, even if it does create a bubbling mess!
See... I'm also cruel to my readers (sorry readers!), because I love having a POV from the 'villain's side' of things and forcing my readers to be conflicted about how they feel. "You were just such a jerk to the MC two chapters ago!! But now you're making me laugh?! GAHHHH!!"
I mean... it does make sense that we would feel guilty about doing such cruel things to our MCs. They are basically a piece of ourselves--or at minimum feel like a close friend. Why would we be proud about torturing them?! These things just happen on their own. It's not our fault!
