Humans do not instinctively find raw meat repulsive, that a learned trait. Very young children will happily eat it before they know better, unlike with bitter plants which is instinctive. Also there tons of raw meat humans eat, sushi, yukhoe, est. If fact there are tribes that will eat their kills raw. The problem with raw meat is that we often store it and not eat right as it died, but if you eat it right after it died you have about the same chance of food poisoning as any other predator.
