- a virus wants to hurt its host, because it wants to use the hosts biological resources to reproduce
- a virus wants to help its host, because its host is its home
It turns out, that the interests in the first category, are bigger than the ones in the second category. Viruses necessarily must be hurting their host to some extent. The host is a big pile of cells and energy and all of that can be transfered from the host's health to the viruses reproduction.
The second category is trickier. It might help, to not hurt the host so bad, but its not plausible that they would have a way of helping their host in a way that would help the virus.
Viruses often mutate to become more deadly, as they find better ways of utilizing the hosts biological resources. The second wave of the spanish flu was more deadly than the first, possibly because it mutated to become more contagious, which came at the expense of the hosts.
