By the time people die of covid they've already spread the virus. Generally by the time people die they've cleared the virus. It's the inflammatory response that kills them. There's really no evolutionary pressure for covid to become less virulent since people can spread it prior to being symptomatic.

There absolutely is pressure because you spread it for longer & to more people if you’re not horribly symptomatic or dead.
