Gamewise, I think the benefit would be not needing to start a fire. So, in emergency situations it would be a life-saver to be able to consume raw meat.
(What comes to nutrition; hard to say - while cooking might destroy some of the nutrients, it also makes some stuff more soluble for the human gut)
Raw herbivore meat should be pretty much safe - I'd guess ones own fingers would be the bigger source of food poisoning (assuming that your fingers touch both the food, and occasionally also your lips)
Raw fish and raw carnivore meat is a lot more risky, for example you might get some of these :
https://en.wikipedia.org/wiki/Trichinella_spiralisps. here my thoughts are about the meat of a fresh kill - the warmer the temperature the faster raw meat will get contaminated. So, adding this in the game would probably require some more internal tweaking to check how fresh the meat is - on a hot day just six hours might be enough to attract parasites to lay their eggs in raw meat, thus increasing the risk of getting sick after eating.
