Goro Akechi from Persona 5

You know, there are at least a couple of sources of hatred I could list under why Persona 5’s Goro Akechi is a prime hater in video games. He tries so hard to receive acknowledgment from his father that he starts a career as a detective and becomes renowned throughout Japan for his ability to solve mysteries. But even the fame and notoriety aren’t enough, and it sends him spiraling into more intense resentment, even becoming a hitman trying to gain his father’s approval. It’s all for naught, but his hatred for his father isn’t the only reason he’s on this list. He outright tells protagonist Joker that he hates him, and he doesn’t understand how he can gain the approval of others without dedicating his entire life to being loved and respected. He’s a tragic figure, and I feel bad for him. But in all that training and studying to become someone worth his father’s attention, he also accidentally became a professional hater.
