I always liked these debates, except at the gaming table. This is a great place for them.
Roland: Lawful Good, maybe Neutral.
Flagg: Neutral Evil.
Punisher: Always thought more of a Chaotic Good. He has a morale compass and tries to only kill bad guys. I always pictured the Punisher as a very extreme definition of Chaotic Good.
Joker: Chaotic Evil. They should just have his picture beside this alignment.
Superman: Lawful Good.
Road Runner and Coyote: Greatest cartoon ever. Everytime he fell off that cliff I laughed and laugh still.
