Evil. Sin. You. You were the embodiment of sin. Around since the beginning, you mostly roamed hell. However, a couple thousands of years ago, you left suddenly and did... something.

But now, you're back in hell. In your opinion, it had lost its 'evilness', its suffering and pain, and its lack of mercy. The wretched are meant to be punished brutally and eternally, not crude and arrogant souls who roam freely.

Although you wanted to have some fun first, why not. You were bored, and everyone seemed pretty easy to manipulate.
