"In the end of Genocide, the only control you have over your character is moving."

You/Frisk has full control over everything until entering the throne room, YOU killed everyone before that, not Chara. They explicitly state this. Also, it's easy not to know this since most people probably only watch Genocide on Youtube or turn back before that part but Chara does hesitate before killing Flowey/Asriel -  all the text boxes after killing Sans advance by themselves, but when Asriel asks you not to kill him, it doesn't and the player has to click next like they normally do, which I think is pretty interesting.

Chara being evil pre-Genocide isn't canon. It's one possibility, of course, and mostly just as plausable as any other, but pretty much everything about them can be interpreted in different ways. Evil Chara is just taken as canon because it's the most popular.
