I think the main danger with raw meat is harmful bacteria (salmonela, listeria, e coli, etc). Basically the same things that make people sick if they’re present and we don’t cook the meat properly. They aren’t always present, but it’s kind of a gamble to keep feeding a cat raw meat.
You do you. But just so you know, cats that are allowed to free range outside have a life expectancy, on average, about 1/3rd that of an indoor-only cat. Killing and eating wildlife is one of the reasons.
