tolerability and phases, I guess. emo is more "life sucks, everyone is annoying, everything is dark (even though it's a 90 degree sunny day) and they are or aren't financially well off to sit around sulking all day, what's the point of anything, I don't care what happens to anyone or myself" type of deal. "hey timmy, come eat dinner with the family, we have your favorite meal", timmy (or becky) responds "shut up mom, leave me alone, I'll eat when I feel like it"--shuts door in moms face, goes back to his emo chatroom to talk or browse the dark web for entertainment even though he's like 26yrs old and has been like that since he's turned 16; emo is mostly teens/young adults
where goth is more "satan is my leader, demon worshipping, witch, wizardry ", conjuring evil spirits, séances,
emo - the world is a personal special type of hell, pain and everyone should burn in the flames of hell because people suck and need to die, nothing good is in the world, no cure for deep dark depression, finding "joy" in suffering, isolation or surrounded by other emos, society doesn't accept you so you internalize
goth- an adult emo. the world is hell, BUT hell is good and needs to be embraced. turn to the dark side and you can do whatever you want, there's no morals or boundaries, Nothing is taboo or out of the ordinary, the more weird that you are the better, black magic, dark arts, mysticism, drinking blood, no restrictions to what you can do because bad is good. goths don't care if society doesn't accept them, they thrive off negative energy and like self-inflicted punishment
