Why does Grendel try to be friends with the men? what is he searching for? what happen?

Grendel accepts the Shaper's view on religion. Although he doesn't believe it, he thinks it is a beautiful lie. This gives Grendel a sense of identity he has never had. He tries to communicate with the humans out of a sense of brotherhood. Although they speak the same language, Grendel is repelled by the Danes. In the end Grendel's only connection with people is to fight them.
