What I mean by that is I write as a villian and he does all the normal villian things eg slaughters innocents, raises evil dead army, kills protagonists love etc. It would be hard to write, but I think I could do it.
Any ideas would be helpful
One thing the two books I just mentioned had going for them is that, even though the MC's were not likeable, they were powerfully interesting.
And I'm pretty sure that if you can come up with other successful stories of a similar nature, they'd have the same thing in common.
However, you can also end up writing something like Hubbard's ten-book series, which I found hideously dull and pointless, which I think was written from the antagonist's POV because Hubbard wanted to describe all kinds of depravity in what he probably thought of as lavish detail. It was an amazingly dull way of doing things. I only finished the series at all because I was twelve, there was nothing else to read, and I had some idea in my head that it was a sin to leave a series unfinished.
The big mistake, I think, was in not caring about the narrator. Richard III was a truly evil man in Shakespeare's play and never portrayed as anything else... but you can't help but like him a bit. You look forward to seeing how he's going to weasel out of this one nearly as much as you look forward to seeing him get his come-uppance. This, I will read. Villian-protagonists I don't like and can't care about, a la Hubbard - well, these days I put the book down five pages in and walk away.
A classic (though very poorly done) example would be: Anakin killed all those jedi just to save his wife, right? (Yes, Lucas totally failed to convince us all, but a better writer could have done it.)
Also, a bad guy can become interesting through his/her relationship with the protagonist. In my WIP, what fascinates me about the bad guy is how, after so many years of fighting without resolution, he becomes a sort of sick addiction ot the MC. When she's upset and needs something to vent her emotions, she seeks him out. He taunts her, but she can't pull back. He's hooked her. Anywho, I find that to be cool.
Protagonist is the character in the story pushing the plot forward.
Antagonist is the characters acting against forward momentum of the plot.
There is no reason why the protagonist cannot be the bad guy.
Great way to use a absolute badass as the main char.
Or, if you don't want to read it, the movie offers a good "watered down" version of the book.
One book I recall that made some evil people out to be sympathetic was The Secret History by Donna Tartt. The odd thing was that their enemy was sort of the petty evil type. One thing he does is eat a birthday cake left in the dorm fridge which had a note on it explaining that the owner of the cake really needed people not to eat it because they were on student aid. I won't go into what the actually evil people do, for spoilers' sake.
