@The PatriarchOkays, let's see... Firstly, The Joker is
not a great villain because he's a psychotic killer. He's a great villain because his madcap lunacy is the perfect foil for Batman's gruff, dour seriousness. He's a great villain because he's incredibly versatile, going from a buffoonish character who just wants to hit Batman with a pie in public one day and deciding to torch a bus full of orphans the next. He's a great villain because he has a striking motif and appearance, and was doing the whole "evil clown" thing before it became a fad. He's a great villain because he's capable of matching wits with Batman, and is constantly trying to push him into a situation that makes the Bat admit he's a madman like himself (which... Isn't so far from the truth, since Batman is arguable just as crazy as the villains he fights, just far more functional). A lot of classic Joker stories don't actually hinge on him just murdering people. I mean the Killing Joke has him kill one, maybe two people in a plan that hinges solely around driving Gordon insane and it's generally regarded as one of (if not the) best Joker stories. And a lot of the time even if he
is just killing people right and left, there's more to it than just senseless carnage. ...In fact it's
very rarely senseless carnage. Either he's trying to make a point, or he's doing it for comedy value (he
is a clown, after all). He's the kind of character who you laugh at, but then cringe and wonder if you really should have laughed.
And even though he suffers from an immense misaimed fandom (super-sanity, anyone? Makes me roll my eyes anytime someone seriously suggests the concept), he still has little backlash from the superhero fanbase. He wouldn't be so well-regarded if he was just a psychotic murderer who just happens to look like a clown.
...Anyways, the other thing. The villains thing. Um, see, I've been doing this online RP thing for a
loooong time. Cut my teeth on Digimon RPs back in the late 90's (yes, I'm an old crone ;_;). And one thing I've noticed is that when people try to make villains, a lot of the time they kind of... Miss the entire point of a villain. It's hard to explain, but... A lot of the time they just end up being kind of one-dimensional. That statement about "he's a villain so he can rampantly murder whenever he wants!" brings up bad memories of characters that were less foils for the heroes and interesting characters in their own right and more... Adolescent power fantasies and misanthropes trying to be as awful as possible without any comeuppance they would recieve in the real world. I mean I'm not saying that's what your character is, it's just that the statement reminds of so many awful villain characters I've encountered over the years. Half of them wouldn't look out of place in a 90's Image comic (or its spiritual successor, the New 52). I've just grown pretty jaded towards player-controlled villains in RPs, I guess, and not just because a lot of the time they don't really get to do much other than sit on the sidelines waiting for their turn to do villainy to pop up.
I dunno, maybe I'm just not as cut-out for superhero RPs as I'd like to be. I think the main problem is that most people seem to want to focus on grim 'n' gritty realism and basically roleplay the Dark Knight trilogy, whilst I want to do things more like the Marvel cinema universe, or the Big Hero 6 film, or... Not going to say like the silver age because that's often too focussed on wackiness without actually telling a coherent story, but... I guess more emphasis on fantastical elements, as well as making the heroes act like, well, heroes. I dunno, I feel like I'm babbling here and I really should get off my soapbox, but yeah.
