Also, I don't the flu's fatality is calculated against every exposed to the flu but against everyone who gets sick with the flu. If the flu also 50% asymptomatic exposed individuals, that would know it's fatality rate down further for comparison's sake.

We calculate both. Case fatality rate (CFR) is based on patients who test positive, whereas infection fatality rate (IFR) is based on all infections. We don't yet have adequate random sampling to have confidence in IFR estimates.
