They apparently, after realizing that buttercups were poisonous, committed suicide by consuming them. They did it so Asriel could absorb their soul and cross them barrier to claim 6 more and free all of monster kind. So they committed suicide so monsters could be free. Chara HATED humanity so of course they loved monsters and wanted the best for them. They appeared to have been treated badly on the surface (probably at a stereotypical evil orphanage like in movies) and wanted to commit suicide (Asriel said Chara fell down for an unhappy reason). They were adopted into the dreemurr family and loved their life with monsters. After Chara and Asriel used buttercups instead of cups of butter in a butterscotch pie they made for Asgore that poisoned him. Chara and Asriel made a plan where Chara would kill themselves with buttercups (and I heard that buttercup poisoning is a painful way to die so they must’ve really cared about monsters to go through and that pain) so Asriel could absorb their soul. With Chara’s soul Asriel crossed the barrier. Asriel could not find the determination to kill 6 humans though and the humans, upon assuming Asriel killed Chara, attacked him. He made it back into the underground but died some time afterwards. So Chara DID commit suicide so they could free monster kind.
