I agree with wanting to know more about James and Lily's history, but I think Snape's choice to become a Death Eater is pretty clear.
He was raised in an abusive home by a witch mother and a muggle father. In the same kind of logic that Tom Riddle used when he became angry with his mother's refusal to use magic to better things for herself and him, Snape probably had some feelings that his mother COULD have turned his father into a warthog rather than be abused and allow him to be mentally and physically abused. In fact, by the time he was probably old enough to go to Hogwarts, he probably (like many children raised in a home with a downtrodden mother and an abusive father) had a deep sense of hate and a desire to "get even" with his father. That can snowball quickly, to where you're fantasizing about violence against any minor injustice. Since his situation didn't improve much when he arrived at school, things just got worse, so much to the point that he was this thoroughly resentful, angry young man. Then comes this powerful Dark Lord who can punish all those do-gooder snobs from school, and who probably welcomed Snape, with his talent and his not-so-sparkly personality, with open arms.
