for Gaster we don& #39;t even know if the most accepted design is even him, also not to mention him supposedly being Sans and Papyrus& #39; dad or some shit. The you two could easily refer to Asgore and Toriel as he was the royal scientist.
for Chara it fucking pisses me off how people say that they possessed Frisk in the genocide run and did it. No the game clearly states that you are the one who does the murders, stop using Chara as a scapegoat.
Also since idk where else to add it, though I like the concept of the game punishing you for genocide, I really don’t like the concept of “resets”. A person shouldn’t be made to feel bad just for wanting to re-experience a game.
