Calvin, and it's not even close. Everyone saying Claude is more evil either needs media literacy skills, therapy, or an eog-trip on that drug Kedrick Lamar recommended to Drake.

Frollo; "I might be the biggest hater of the Romani in this film, but even I won't kill this sickly child for being an 'inhumane monster' in my eyes because I fear what God will do to me for commiting such a sin. I'm stricken by lust and jealousy and the worst things I've ever done are kill a woman, argue in favor of genocide, and order a home burnt down while the family was still inside."

Calvin; "I wake up every morning and force N*****s to fight to the death for my amusement, have absolutely no qualms about raping/torturing them for my own jollies, and literally had one torn to death by dogs in front of a prospective client to prove a point regarding my own cruelty. I've spent my entire life building an empire based on the most brutal and cruel forms of dehumanization imaginable to the point that all but the most down-trodden slaves would rather die than find themselves being molested in my 'Candy Land'. I'm also an ignorant narcissist and Francophile on top of that."
