Viruses are not exactly living organisms, so the comparisons you make are not apt. There's a huge difference between any virus and an organism which plays a role in a super complex ecosystem (and our food chain) we don't entirely understand.

Yes, humans have driven many species to extinction but I think in retrospect this would have been inadvisable.
