Generally, it is not in the reproductive interest to kill the host ( anthrax is an interesting exception). What gives a virus a reproductive advantage is keeping or increasing the length of time it can output virus from the host to infect others, and/or making the success rate of spreading increase. So becoming more deadly is a competitive disadvantage if it decreases the ability to spread.If I can change he topic for a second
mutations:
With the soon to be out of control spread of delta around the world is there any chance we have a mutation that makes it more contagious, so that it becomes the dominant strain, while being significantly less deadly?
If so is this statistically less likley to happen then a mutation that makes things worse?
From what I have read virus is more likely to evolve to a less deadly form if that ( or another mutation it has) increases the selective bias in the favor of that variant . (Increases the chance to spread).
The increase ability for delta to enter host cells and thereby replicating easier gives it an advantage vs other variants that exist now.
