hardest decision I've ever made in my entire gaming life

Try OuterTale genocide

I might some other time.
I'm trying to play all the games that are referenced in indie cross so I can watch all of it

a shit here we go agin

I'm fairly certain it's actually called the Chaotic route.
Also, spare Papyrus. Later, he'll call you when you're about to encounter an enemy that you should spare/not encounter. It's a much better ending, trust.

oh believe me: you didn't
there's a secret ending other than "return home" and "return the sun"

oh

just delete your safe file
and restart the game
everything will be clearer (tip (not a spoiler, just a tip): go to the mine in the barrens when you can)
