How is grendel's world view and self-concept affected by his experience with men? how does this event affect his relationship with the "old shapes" and with his mother?

He shows contempt for nature, especially spring, because its life and rebirth undoes his destruction. He sees flowers as landmarks of past murders: "Here, I killed the old woman with the irongray hair. She tasted of urine and spleen, which made me spit. Sweet mulch for yellow blooms" (p.7). This reveals that Grendel is disturbed, pessimistic, morbid, and perhaps evil. It also shows his absurdist, existential outlook on life. We are but food for worms; there is no greater meaning behind life or death. He also says that he used to take pride in striking fear into innocent woodland creatures. His middle finger to the sky is a good depiction of his defiance to the prospect of any higher order or spiritual entity.
