Let's have a little thought experiment about Right to Life:  Suppose a woman has an unwanted pregnancy, maybe from a sexual assault, and is denied an abortion.  The child, a boy, is raised in a single parent household with limited means, let's say because her education was interrupted which relegated her to low wage jobs;he has limited adult supervision because she has an erratic work schedule and cannot afford child care. He has trouble in school, for a variety of reasons related to poverty.   Let's say he is bullied as a result and finds companionship in the only group that will accept him, which eventually leads him astray.  

Time goes by, one thing leads to another:  juvenile delinquency, arrest leading to more arrests, prison, falling in with a tougher crowd, then harder crime that eventually involves gun play.  He's sentenced to the death penalty.

This human life is still lost at another human hand, but with other lives lost along the way:  The Law of Unintended Consequences.
