Travel to the southern portions of the wasteland, where the number of radscorpions and ghouls is high.
Attack and kill any radscorpions and ghouls that you encounter. Each time you kill one, you receive a notification that your karma has gone up.
Travel to the northwestern portion of the wasteland, where there are a large number of fiends (drug-addicted criminals that will attack on sight).
Kill any fiends that you encounter to raise your karma.
