Overview:
This esp-free file sets all creatures in the game with "evil" or "very evil" karma to neutral, to prevent gaining karma from killing them.

I find that the notion that killing abominations grants karma because you're "purifying the wastes" is tenuous, and it also assists in making it really easy to always have good/great/maxed positive karma.

This does not alter the karma of "good" or "very good" creatures, as I feel that the karma penalty for killing certain non hostile creatures is appropriate.

If you would like to alter the script to do so, simply change the line
if GetBaseAVAlt Karma rRef < 0
to 
if GetBaseAVAlt Karma rRef != 0
and save the .txt file.
