Thanks. A distressing thougth indeed.
Its seems very plausible that the lottery in the gene pool among bats and other critters, particularly in Asia, is constantly producing a wide genetic variation in different sorts of virus. Some will by chance turn out to be able to spread easily between humans. Some will have a high mortality rate. Some will have a high number of non symptomatic carriers, some a low number. Some will spread easily and kill swiftly. Its a genetic lottery thats been with us since the dawn of Earth. Sooner or later there will come along a giant killer like smallpox again.
Its basically a very educational example of the Evolution thesis of Darwin, clearly showing us that no matter how clever and civilized homo sapience has evolved into, we stand no chance what so ever against Nature.

Let's take this^^ one step further.
If you accept Darwinian theory, understand it is about survival of the specie, not the individual. Be it mammal or virus, mutation/change/evolution must be to the advantage of the specie. If a virus is an extreme killer of its host, it will die out along with a great number of the host specie. If the virus does not mutate, it will die out. The ability to mutate is in the RNA of the virus as a survival tool. A virus that can infect a host, and not kill it will survive. A mutated form can reinfect a host that has immunity from the original form, thus perpetuating the survival of the viral "specie." Ideally, for the virus, mutating to a form that allows its existence without killing the host is the end game.
People speak of the Corona virus as "smart." It is not smart, it is programmed for survival and its means of adaption is mutation and reproduction. It is vicious because it has developed a rapid reproduction rate from being in the bat community where it exists without killing the hosts. Bats that have "evolved" to live with the virus by developing rapid response antibodies and moderated inflammatory reactions. The virus responded to the bats by developing a rapid reproduction rate that allowed it to live inside a host that developed a tolerance. The bats are infected but asymptomatic . The bats survive and so does the virus. The bats are contagious. Eventually, the bats will transfer the virus to another bat or specie of animal that has not adapted to the viral infection and the new hosts (individuals) will succumb. The surviving new hosts will be those whose systems were able to adapt to the viral infection and become the "stronger" version of the original population.
Meanwhile, the virus adapts as well, through mutation.
