Just going by the definition of purpose, which I would take as the reason viruses exist. I think there could have a purpose in their “actions”, such as changing enevelope tropism to broaden target cell range, or more tightly binding a cellular protein to inhibit antiviral defenses. But to me, a non-living entity like a virus itself having a purpose for existence beyond making more virus sounds philosophical or religious— which is fine, but just not how I think about it.
