Watched every Family Guy episode, Peter Griffin’s total kill count is somewhere between 1000 and 1500
Saw that episode where Wild West asks Peter if he's ever killed a man and wondered how big his kill count actually is. While it's hard to give an exact figure, I noted all the moments where Peter intentionally and unintentionally took someone's life and it adds up to roughly 1000 to 1500, majority of this figure being made up of the time he won a marathon by running over hundreds of people, the Oklahoma City bombing that he admitted to being involved in and a ton of random explosions and massacres he caused. Still feel like I might be missing a few though let me know if I'm missing any. He's killed lots of animals too but don't think they really count because they're not sentient.
