WHO IS DEADLIEST!?

Brief History
Marv was born in The Projects and had a rough childhood. He was very protective of his doting mother, who eventually got sick forcing them to move to a better part of town. The Projects had already toughened him up, and left with it's residents as useful allys. In school his only friend was Chuck, a retarded kid who thought Marv was genius. He also got a gun from a dead kid, and he named it Gladys after one of the sisters in school. Once he went to camp, but since then he hated nature and trees. Trees and the creepy sounds of nature were the only things that scared him.

Some time after that Marv joined the army and went to an unnamed war (heavily implied to be Vietnam) where he probably developed his scars. He also would later suffer from a 'condition' (that might have been Post Traumatic Stress Disorder). He took pills for it, which he got from Claire, shrink Lucille's girlfriend. He always had a respectful fear of his 'condition' fearing he would turn into 'what they always said I'd turn into. A psycho killer'. However he always trusted his instinctual "cold thing", a feeling like a snowball in his stomach, something above his perception that told him that something was wrong (for example, he felt it when he approached the RoarkFarm)

Once he suggested Lucille to get a treatment to "cure" her lesbianism, but she punched him.(from Sin City Wiki)
