/lit/ - Literature

My uni dissertation is going to be on the topic of villains, so I was wondering if we could get a discussion of villainy going? Not asking you to write it for me, but it'd be nice to have ideas to bounce around.

>What makes a great villain?
>Who is the single greatest villain in literature, in your opinion?
>Which novels/films would you recommend I check out for their villains

Whatever thoughts you have would be greatly appreciated lads
