The protagonist from for instance Mark Millar's "Nemesis" is not an anti-hero, but a complete villain.
'The marquis. Well, you know, to be honest, he seems a little bit dodgy to me.'
'Mm,' she agreed. 'He's a little bit dodgy in the same way that rats are a little bit covered in fur."
Millar's stuff will always be an outlier, because he indulges in that kind of "fk yeah let's kill and rape these guys" with the protagonist, but I do think villain protagonists are often going to be antiheroes. Case in point, Lex Luthor. He's still evil as a protagonist, but it's a different perspective.
That said, I wholly agree with your earlier comment about Catwoman being less interesting for always stealing from bad people. I want to see her take what she wants without much regard for others. Show what the world's greatest thief would actually be like, and show the effect that it would have on people. I mean, the only times we ever see he people she's already stolen from is when they call mob/supervillain vengeance down upon her through their criminal connections. Seeing old people's lives disrupted would be a lot more interesting and would present Catwoman in a much more interesting light.
Looking for artists, know I won't find any. That blows.
