Well, philosophical questions indeed.
Do they kill with intent? Can a non-conscious being have intent? Can a microbe celebrate in a way which is ascertainable to the human eye?
So you might say the comparison is flawed from the outset, being based on an unworkable foundation.
But even pleading in the alternative - I woauld say a microbe kills with intent in as much as a microbe can because that is what it exists for.
You're also not taking into account the fact that people are commonly accepted to have some form of human rights and worth as a person which viruses are not. That's why you're out of order on that one no matter what you say about intent.
You don't see anyone Palestinian as human? Too bad... alas... your hang up.... whatever. They are.
