Both IGA and MS's Draculas are tragic characters(IGA's is more the tragic asshole, MS's is the tragic anti-hero). I'm done with sympathetic villains. It's true, sometimes they can work, but the problem with people(in general) is when they pay witness to something good, they want it in spades. It's the reason why, with trend and things in general, mankind KILLS IT for themselves. You can't have just one good thing, you want it all the time, ad nauseam. Variety's the spice of life. Not every character should be developed the same way, and just because it works for some doesn't mean it would work for all.
The problem is that people are only really comfortable with two types of villains: tragic villains (LoS: Dracula, Mithos Yggdrasil, Kuja) and pure evil megalomaniacs (Zeromus, ExDeath, Kefka, Zeus). The people who like the former criticize the latter of being too shallow, and people who like the latter criticize the former for being not evil enough, etc, but both of them are justifiable. People can either sympathize, or just write them off as "evil".
I want to see the third type of villain, the real villain, the villain who doesn't see what he is doing as evil at all. I'm not talking the whole "Well, it's just two sides of the same war" where they try to paint everyone involved as partially at fault. I want to see a Hitler Dracula. I want to see that Dracula who will commit insane atrocities because he believes it's right, not because he's some indoctrinated zealot, not because he's pure "evil", not because he's insane. A Dracula where you can sit there and go "Well, I can see your perspective, but I can't understand it all. It's wrong." And no "I must destroy the world to save it!" That's not what I'm talking about.
It's like where people see those gifs of Hitler having fun and being a normal person and feel uncomfortable because they think "How could he do that? He's pure evil. He doesn't have real people emotions." I want to see a Dracula like that. A Dracula that commits supremely evil acts, but still has his emotions. A Dracula that wipes out entire cities, but weeps when a Belmont kills his own son. It's kind of like LoS Dracula, but minus the "I used to be a good guy".
Sure, it might lean more towards "tragic backstory", but I think that's just because the nature of character depth. A character with some depth is always going to be more understandable than one without depth, but it's the depth that makes them interesting. It's why Dracula is a more interesting villain than Satan, because Satan is just pure evil. I'm just not a particular fan of characters that are evil for the sake of being more evil. Everyone has motives, and I think going into those motives makes for a far more interesting narrative.
