I think that because Chara's kind of a ghost thingie she saw Asriel's death, and probably had the same backstory as Asriel aka how Flowey happened. She learned humans had no mercy, and that to survive you need to kill or something. It was also kind of noted that Alphys has something to do with it, since the true lab literally has a RED SOUL in the power room stored in a BLACK container. Maybe Chara's soul became black, Asriel also got corrupted with that? Maybe the red soul in the true lab is Chara's soul, and Alphys injected the determination into it, since Flowey is her first experiment. She then tried it with Chara, but human souls might have another effect even worst than the amalgamates made from the monsters' souls. its just a theory idk
