I was very hesitant to join this discussion due to the question being asked in some wacky pseudo-phylosophical way.

Why play evil? Can we for a second pretend that it is not a very complex question. Here is my easy answer.

If you roleplay:

- It can be a state of mind as a result of a past trauma
- It can be a state of mind due to the history between groups (evil to some, kind to others)
- It can be an external condition altering your state of mind (Durge be like)
- Evil deeds can be performed out of necessity, with a gun to your head

If you don't roleplay:

- Can take things from others
- More combat
- More experience
- Morally dubious yet quicker and easier solutions to quests
- Can punish anyone talking shit immediately
