Each word of Heraclitus expresses the pride and the majesty of truth, but of truth grasped in intuitions rather than attained by the rope ladder of logic.
Whether we had a (good) moral intuition more developed, we would be as much morally disgusted by the rapacity of those who try to benefit from, and monopolize (or secure or corner), having no consideration (regardless or irrespective of) for others ("autrui", Fr.), than we physically are by a sickening (or nauseating) smell.
Learn to let your intuition-gut instinct-tell you when the food, the relationship, the job isn't good for you (and conversely, when what you're doing is just right).
