I mean... He kinda acts in self defence, but the worst thing that is ever done to him is a pie to the face. To which he reacts by viciously slaughtering his opponents. Who are - admittedly - piñatas. But they’re sentient piñatas. That are sliced open and gutted! And then their insides are devoured while they’re still alive!!! How is that not murder in this universe???
This is basically Disney’s Cannibal Holocaust. I find this deeply disturbing.... (Not that I don’t like it, mind you... ;) )
