Damn.
I realy wanted to stay evil, but doing major quests increased Karma. I even massacred whole cities but my Karma got only bigger. Now I'm a champion with 300+ Karma.
'Guess that the hard part in evilness is not surviving as it, but staying as it.
Maybe there are some quests you haven't done on the evil side. My current character is a level 20 slaver/child killer/grave digger (Helps lowering karma)/pormstar and every other six-related perks with -300 karma.
What really lowered my karma is the Modoc quest where you must investigate on the nearby "ghost farm".
Spoiler The innocent Slugs there didn't live to see the next sunlight after they dared capture me.
Another trick, be rude to everyone (Except the goodfellas at New Reno). Even if it blocks a goodie two shoes quest. My Slaver, although he
Spoiler slain the raiders camp and blew up Gecko,
can't be accepted by Citizen Lynette. So I simply called her a [censored] and went on my way.
Reputation wise, my character is mostly vilified or neutral. He's only idolized and liked in The Den and New Reno.
Spoiler By the way, eliminating the Wrights family in New Reno will give you negative karma. Just don't kill the children or New Reno will hate you. Eliminating the other families will give you good karma.
I did not slaughter whole towns. (
Spoiler Only the Ghost Farm, including the children
).
