Raw meat is a ferrets natural diet - they are strict carnivores
Feeding ferrets a natural diet does not cause them to bite. I have 3 ferrets all of which are fed a raw diet.
There is no connection between feeding a diet that is natural to a ferret and aggression towards humans. I can tell you this from my own personal experience and the experience of others both in present times and historically.
Feeding ferrets raw meat will not cause them to bite. Ferrets are strict carnivores - meat eaters - they have to eat meat in able to survive and before they were domesticated, raw meat was the diet. Ferrets naturally bite as young kits and need to be trained not to bite. Abused ferrets are "fear biters"
