* Pretty much the whole point of the musical ''Theatre/{{Wicked}}''. Also contains usage of AristocratsAreEvil.
* The musical version of "{{The Phantom of the Opera}}" zig-zags this: the Phantom does have sympathetic qualities thanks to his FreudianExcuse, and "Music of the Night" is basically this concept set to VillainLoveSong--but he's still not a nice person and gets progressively worse as his CrazyJealousGuy side takes over. He ends up with a LoveRedeems ending, however.
* Theatre/TheMagicFlute [[spoiler:[[SubvertedTrope subverts]] this. The Queen of the Night actually is as bad as she sounds.]]
