I have questions~!
What is the definition of evil?
What if your alignment is several shades of black and white but mostly in-between?
What if you're not /objectively/ evil, but you follow the traits of it in the benefit of all?
Does doing evil things make you objectively evil?
Is not following the path of the Light, shamanism, or any sustained idealisms of Azeroth metagamey/godmodish?
Serious questions :<
Worthwhile questions and a thread in their own right, but really not what this one's about. This is a thread chiefly about the IC/OOC divide and how to navigate it while engaging in the emotionally charged atmosphere that frequently comes when RPing an antagonist. Whatever the motivations of your character, how you interact with your fellow players should be the same in any of these situations.
That said, these are interesting issues you bring up and I'd love it if someone makes a thread to discuss them. Villains, as I noted above, are the things that drive stories, and explorations into the subtle shades and myriad manifestations of villainy can help us all as storytellers and roleplayers.
