How thin is the line between anti-heroes and anti-villains?

According to your understanding of anti-heroes and anti-villains, how similar are they and what's the main difference between the labels?

An anti-hero is a person who does good deeds for non-heroic or even villainous reasons, and often with villainous tactics. Like Wolverine. He’s hunting Sabretooth because he wants to rip out his tongue, but in doing so he’ll save this van of schoolchildren. They may even do villainous stuff from time to time but the heroism outweighs it enough to keep them in the blue. Batman is not really an anti-hero.

An anti-villain is a person who does bad deeds for non-villainous reasons or even heroic reasons, and often with heroic tactics. Like Dr. Doom. He’ll happily destroy the world trade towers if it means stealing the tech in the basement to ward off Galactus. He thinks he’s this amazing guy, but in reality....

They may do truly heroic things from time to time, but the continual villainous means outweighs it enough to keep them in the red.

I don’t think it’s a very thin line, they’re farther apart than anti-hero and regular villain or vice versa.

^ Bizarre bordering on wrong interpretation.

The line isn't thin at all.

A hero is someone who does good deeds and in a way that society deems as heroic.

An anti hero is someone who does good deed but not in a way that society deems as heroic. Deadpool.

A villain is someone who does bad deeds and in a way that society deems as villainous

An anti villain is someone who does bad deeds but not in a way that society deems as villainous.

It's pretty simple.

A morally grey character can be both anti-hero and anti-villian, it depends on which side he's on at the time.

One is a full time hero and the other is a on and off hero.

@havenless: you mixed up those two words and definitions lol
