Of course she shouldn't do "life". But, your line of thinking is part of the sociatal problem, here.
A woman has sex with a young boy, and it is "Way to go, Stud!" "No victim here!" "She's a frail young thing with some troubles in her life....."
A guy does it with a 14 year old cheerleader, and he is the most disgusting person in the city. "Lock him up!" "Keep him away from my daughter!"
Who are we to say he was harmed or unharmed? Only time will tell. Are girls harmed when some old goat screws them?
In a lot of cases with older women seducing young boys, the kid has an "older" or more mature appearance. He is usually a "rough edges" kind of kid......a "bad boy". (Gang member, problem at school, etc) I wouldn't be the least bit shocked to find this to be the case. Often it is someone of a differing race. So the woman is crossing into several "taboos" in one fell swoop.
She needs some help, and prison has never made someone a better person, IMO, but that is still where she is headed.
