How Can Something Lifeless Cause So Much Trouble?

So it isn't clear whether or not the coronavirus is alive or dead. There are differing definitions of life. But regardless, it is well known that chemicals react with each other. There are the well known chemical compounds, carbon dioxide and H2O. The chemicals involved in a virus are much more complicated organic compounds, but, nevertheless, they are all things that react with or are attracted to each other. The building blocks of life, DNA, are all made up of things that react with each other to create very complex chemical compounds. We might assume that all that is needed for life to form are these chemical reactions. But still there is something missing even when all the chemicals are present in the right combinations - some kind of spark that would turn a non living compound into a living compound. A virus like the coronavirus is a very simple form of life consisting of a single strand of RNA wrapped in a protein "envelope." So how can such a simple thing which, depending on your definition of life, is either alive or dead wreak so much havoc?
My theory is that it can't be explained by chemical reaction or attraction. There must be something else going on. There seems to be some intentionality to the virus. It knows enough to invade human or animal cells and use their material to make copies of itself. It is self-replicating using the host's contents in a parasitic manner. Just like many life forms, a virus wants to make copies of itself similar to what animals and humans want to do. This is one of the characteristics of life. Parasites invade hosts and use the host to further their own interests, and one of their interests seems to always be to expand their number. So maybe the definition of life has to do with intentionality and reproduction.
It certainly has to do with evolution. Darwin explained evolution, but it may not only have to do with random mutation and natural selection. Random mutation is one thing, but maybe there can be intentionality as well. Consider hairlessness. It could be just sexual selection that less hairy apes were considered more sexually attractive so that eventually hairier apes died out as the more hairless ones reproduced. Or maybe subconsciously apes came to desire less hairy mates, and that subconscious intention caused a genetic change which determined the hairlessness of their offspring. Or it could be a combination. The same process could be true insofar as standing upright. Apes can do it, but it's not as comfortable as being on all fours due to the bone configuration in their hips. Maybe a desire or intention to not be on all fours led to a genetic change in the configuration of their hips. Eventually that's what had to happen so that standing upright is more natural for human beings than being on all fours.
Russian scientists have domesticated foxes after natural selection of the more docile ones over a number of generations. They've also done the same thing with wolves, but they found that as non-aggressive as these wolves are with humans, they are still not able to bond with human beings the way dogs do. They think that's because docile wolves are still not genetically identical to dogs even though dogs evolved from wolves. Perhaps the docility of non-aggressive wolves led eventually to the genetic changes that created dogs who are both docile and capable of bonding.
What this boils down to is that scientists still don't really understand what life is and what evolution is, what forces lead to the origination of life, whether or not those forces are ubiquitous in the universe or not. Just as human beings were potentially part of the universe even before they existed in it, maybe the universe has this potential everywhere under the right conditions. Maybe it is part and parcel of the universe rather than something added to the universe. If so, then we would expect that there would be life in many places in the universe in addition to planet earth.
