my tips for being evil:
1)carry a big mace and smash all the little chilren in verdistis
2)if you want to be evil carry poison potions, then throw em at people, they choke to death on the poison.(very good for mass murdering and no loss off rep.
and 3)tell everyone to **** off when they talk to you then mace em good.
hope this helps you become evil.
P.S. yes, i know, you still be a good guy but just play along ok?
