Intention is everything. One does not suffer for unintended evil actions, and one is rewarded for good intentions. The emphasis of Karma Yoga is not of tracking good and bad deeds, however. Karma Yoga is wisdom in work and action. The Karma yogin sees, experiences, and confronts everything with great awareness - sees it as it is, never judges.
Nothing is either attractive or repulsive, it simply is.
Mahatma Gandhi exemplified the spirit of Karma Yoga.
