To all Adventure Time fans: Embrace ALL the qualities of the characters, of all your favourite characters particularly
If your character has issues, don’t feel like they should be changed - accept them.
If Marceline’s your favourite character, embrace her selfishness.
If Ice King’s your favourite character, embrace his greed.
