Evil Vs. Evil

This category refers to morally-dubious characters whose main enemies are other villains. Many extremely dark works, such as Warhammer 40,000, base their main conflicts around this principle, and nearly all protagonists are portrayed mainly fighting individuals who are either similar to or clearly even worse than they are. Not every villain who has ever fought another villain should go here. Villains only belong if this applies to most or all of their activities and is a significant aspect of their character and if they are seen as "heroes" in their setting due to the extreme levels of wickedness committed by their enemies.
