Why is the advantage to bacteria/viruses that kill a host?

Question

Would it not be more advantageous to be relatively benign and keep on spreading itself around rather than kill the host?

Edit: I meant, “what is the advantage” not why.

The discussion here is a bit misleading. Viruses always kill their host: the cell they invade. They reprogram the Dell to produce viruses. If an animal or human looses too many cell, he obviously dies.
