1. We know Chara hates humanity, but we don't know necessarily that that's the reason they came up with the plan. They could've done it because they believed it was necessary for the monsters to live on the surface. Even genocidal villains can have sympathetic motives.

2. Chara cared about them in the past''. ''That might've changed in the Genocide Route after Asriel's betrayal. There's also the "Mr. Dad Guy" sweater that Chara made for Asgore, which implies that they cared about Asgore enough to make him a gift. The laughing at his buttercup poisoning could either be an evil laugh or a nervous laugh in order to cope with the situation.

3. Chara controlling Frisk is exclusive to the Genocide Route, but it's possible that they're the narrator, which means their guidance would be in all routes. There's no certain way we know that Chara's narration is exclusive to Genocide, and the laugh interaction with Snowdrake's mother could be used as evidence to suggest they were present in the Pacifist Route.
 * You laugh, and keep laughing. It's SO funny, you can't stop. Tears run down your face. | ... what? You didn't do that?[Laugh]
