one homunculus: envy
"Envy. You’re jealous of humans. Humans are supposed to be a lot weaker than you homunculus, but even if they get discouraged after being beaten, and even if they get close to falling down after losing their path, they continue to get up and fight. Everyone around them helps them get on their feet. And you’re envious of those humans."
