The blue eyes rule only applies to werewolves and werecoyotes, as far as we know. Theo is a Chimera, the rules of the supernatural don't apply to him, which is why his eyes didn't change colors. Just about every villain ever introduced on the show is a psychopath, so following that logic, all of them would have green eyes.
