These 3 in my opinion sorry if I make you sleep while you read
1.-Miguel Rivera: For one thing that at first might be to quick to notice but when he told Imelda "This is my life, you already had yours", doing this to a deceased person on the Day of the Dead can be easily considered as an extremely disrespectful and rude comment since it's basically telling a deceased person to not mess with you since they had a life to do it to another person, and I tell this as a mexican myself.
2.-N (Murder Drones): Even if remorseful he commited several crimes like mass murder of thousands, mutilation, cannibalism and was basically part of a genocide. Also in the 4th episode when he was counting the campers and one of them was killed instead of calling N out for it he simply said "that's everyone" and whispered "minus one" showing no concern for the poor guy.
3.-Oogway: To say that he alongside his former best friend Kai were basically conquerors and even Kai gained several titles that give away that he was a mass murderer, also he "did" betray Kai and even his army in exchange of the pandas for healing him despite Kai being the one who carried him for days seeking for help when he was badly injured, also since he could foresee the future I arguably found him a bit of an extremist as seen with the Secret of the Masters short with his teaching methods with Master Ox, Croc and Thundering Rhino, and the Secrets of the Scroll short when he had Shifu sick in order of Tigress forming the Furious Five out of accident and even allowed Boar to beat her up in order to not interfer her destiny, something a bit hypocrital considering what happened before with Tai Lung by never telling Shifu to not fill his head with dreams of being the Dragon Warrior and he did only interfer when he tried to take the scroll by force but he did nothing when he destroyed the Valley of Peace.
