You’re right about this Anon. Maybe attempts to portray him as “green-eyed” monster — angry, unstable, full of rage, etc. Think “How the Grinch Stole X-mas” where theGrinch has green eyes while he’s evil, but then his eyes turn blue when his heart grows, etc. Also, tiny dark pupils make him look like he’s grimacing when he actually has a pleasant look in his eyes with a natural smile.
