Judge Claude Frollo might be the most terrifying villain Disney ever created.
Not because he's the strongest. Not because he has magical powers. And certainly not because he's particularly clever.
Frollo is terrifying because he genuinely believes he's righteous.
The Hunchback of Notre Dame, Disney created a villain whose cruelty isn't driven by greed, revenge, or a desire for world domination. Instead, Frollo uses morality, authority, and his own rigid worldview to justify everything he does.
