Undertale

[AWA1997]

Ah, I see. I like that explanation. He's still creepy though.

Spoiler:

I figured that his hate for humanity was along the lines that he felt what humanity did to the monsters was unjust and horrible, so he tried to rectify it, potentially... I thought he actually went to the top of the mountain to commit suicide. But ended up falling through instead. But, like, who wouldn't know what was up there at the top of the mountain? I dunno, haha. I bet there are many theories surrounding this game... for many parts of it!

I think I phrased that wrong in the first part XD

Spoiler:

Yes, most people do think he went to commit suicide. When he jumped down, however, instead of dying, Asriel found him and Toriel and Asgore adopted him as their second son. He saw how much they wanted to leave and knew that they never could unless someone died. When they accidentally poisoned Asgore, Chara swore Asriel to secrecy and put his plan into motion. In fact, Chara's plan would've worked, except Asriel refused to fight and ended up dying and making Chara die in vain. That's why most appearances where Flowey and Chara meet, Chara refers to them as a traitor or something else along those lines. Asriel had the power of a minor god, but refused to use it.
