No human alive would commit genocide for nothing, there had to be a reason, and not because "the humans were not nice" thing, that not a reason. I think Chara was a bad apple, not evil (Yet) but not truly good, bullying (Or being bulled) and maybe hung around some bad friends, that kind of thing.

Also she/he seemed to have some kind of emotion control over Asriel as well, that may have help in going with her plan to free the monster, hell if Asriel really wanted to he could just tryed and talked her out of it or told goat mom and goat dad. A true best friend would relize that there adoptive brother/sister was doing something really stupid and try and get them some help or stop them, but no he sat there like the stupid goat he is. (Im ranting sorry.)

Anyways, when Chara killed her self, with good intention of course, i think she got corrupted by the power that they held and wanted more, but Asriel rebelled and in doing so ejected Chara out of his body. Chara was later reborn as Frisk, a name she made up, where she wonders the underground, like a lost spirt, looking for her purpose in this new life.

Of course this a  thero back by nothing, so yeah.
