This one isn't that bad actually.
Yeah, I have to agree that some fanfolk of villains take their...infatuation a tad too far and/or too seriously. Its always the attractive ones, too; I've never seen someone with the hots for Ursula from The Little Mermaid.
Honestly, though, I REALLY don't get being attracted to
any villain character. They're. The fucking. Villain. Unless its topsy-turvy Ayn Rand world where good is evil, then villains are villains because they're god damned evil! Loki is the villain because he's a murderous megalomaniac, not some poor widdle thing you can fix with a blanket and hot chocolate. Voldemort is basically Wizard Hitler, Jr., since I believe Grindlewald was the first Wizard Hitler. Are they fascinating characters with interesting personalities? Sure, but they're still undoubtedly, unabashedly
evil. Its like why I never go for the "fuck the guy who shot you in the head for a platinum poker chip and left you in a shallow grave" option in New Vegas. I always just go into his casino, guns (or fists) a-blazing, and turn the fucker into human giblets.
