Survival is a biological imperative, not an intelligent one. Evolution is a blind mechanism, it doesn't just suddenly decide that a bird needs a different beak or that a bacteria killing of its host isn't a viable long-term survival stategy. The bacterium just does what it does because it has evolved simply to survive being killed by the immune systems of its potential hosts. Flu can kill people, but you're not gonna say that the flu virus is intelligent, now are you?
