No, I´m saying that technically the player is the one who causes the genocide run, not Chara. Chara is narrating for you and in the pacifist run, and you can see their sense of humor through their narrations. Chara allows you to save Asriel. You don´t have good memories with Asriel, making it impossible to save him, but Chara lends you their memories, hence the flashback with Chara falling down. Chara ¨Laughs Asgores Buttercup Poisioning off¨, but if you look closer in the game, a lot of characters make references to laughing the pain away. Chara didn´t fall from the underground without a reason, it was to end their life, which probably means they were abused by humans, but Asriel and the Dreemurr family gave them hope. They loved their family, but wanted to save the monsters. But in the genocide route, you, the player kill everyone, and they are forced to watch. That makes them think the only reason they were brought back was to kill everyone. Imagine seeing your sibling being killed by humans, which is the last thing you see before death, and then suddenly you wake up and see a human, who you have to follow around, is killing the monsters, the only people who cared for you. Remember, Chara is still a child, maybe somewhere between 8 and 12. They are easily influenced. Flowey is killed at the end of the Genocide route with such force, because Chara needs to kill their best friend. Their brother. But they believe this is all for power. You killed everyone for a reason, right? In Chara´s speech, Chara tells you they were grew stronger with your rising Exp and Lv, and that they thank you for bringing them back. They grew more corrupt over the course of the Genocide route because they want to think you are killing for a reason. When fighting Toriel, Chara goes quiet because this is their MOM and during the Undyne the Undying fight, they call her the true heroine, because they believe Undyne can stop you, as you can tell before they are corrupted by you. Before you say that Asriel said that Chara wasn´t the greatest person, Monster Kid calls Undyne a jerk after she attempts to kill you in the Paci route. Everyone else is forgiven for their sins, but Chara is not, and they only killed themselves. Let me remind you, Papyrus literally tries to date like an 8 year old and tries to capture them with lethal traps, Undyne literally tries to kill you and will not spare, and others too. YOU chose to kill or spare everyone, not Chara. They are used as a scapegoat.
