I think this because Pete obviously has a tragic backstory and even Chip and Dale try to reason with him to be friends and tell him how they feel his pain. However, Pete throws that remorseful moment away by saying: "You two really are the worst actors in Hollywood!" And by the time he became Frankenpete he endlessly chases them and still tries to kill them. That idea of Pete deciding to ignore Chip and Dale's offering of peace and continuing his bootleg rampage to gain more money and become the most feared criminal sounds very Genocidal as Pete no longer remembers his tragedy and enjoys the terrible torture he does to Toons. What do you think?
