Is there an 'evil pays' kind of mod?

I find that BG makes it impossible to roleplay a neutrl evil or lawful evil character. Not only 90% of quests are about rescuing stray kttens in the fist place, but those few which allow multiple resolutions grant better rewards to 'selfless' characters. Is there a mod which tries o address it? Even good characters would beneit roleplaywise by making the sacrifice/offer meaningful.
