Hope you're right, and we're not keeping a bunch of marginal immune systems alive through heroic efforts just to breed more variations.
viruses don't mutate for any single reason, it's not directed evolution, it's errors in transcribing their own gene code in duplication.
That's what most evolution is. For sure. Not imagining there a will behind it
Mutations don't happen for a reason, but long term trends in widespread mutations absolutely do happen for a reason, namely that they meaningfully contribute to the organism's ability to reproduce.
Killing the host doesn't do that nearly as effectively as giving the host a minor cold that doesn't even make them feel like they need to change their routine.
and sometimes, even horrific shit like rabies - can kill the host and still be viable for reproduction and future variation.
just because it kills the host doesn't automatically take it out of the gene pool before it can cause enormous harm.
