Why do viruses want to harm the host?

I dont get why viruses want to attack and harm living things, some virus kill their host, but this goes against nature because if the host dies, the virus dies. If their sole intention is to multiply and kill are they nature's weapon?... so what are their purpose?

They don't want to hurt the the host, they just require the hijacking and usually lysis of the host cells to continue their ''life'' cycle. I put life in quotes because technically they are not alive, they are small machines that harm host cells as a consequence to their machinery

Viruses do not ''want'' to do anything - it is silly for us to impart desires to things that are barely considered alive. Viruses operate simply according to evolution. A virus is a simple genetic program - infect, divide, spread. If this strategy results in it spreading and surviving, then it will continue, simply because the program works. Sure, some viruses kill their host, if that's a successful strategy - if killing their host allows them to multiply more and spread, then that will work, and that particular type of virus will go on killing and spreading, simply because it continues the propagation of that program. Other viruses succeed by doing the opposite - staying dormant and multiplying at a more modest rate.
