Distance and Difference Quiet the Conscience

A comparison: With abortion, the killing is made easier because the object of the violence is not seen - or at least not clearly-seen. The same thing applies for wartime high-altitude bombing/firing missiles as compared with hand-to-hand combat on the ground.  When close proximity cannot be avoided, and just like in wartime, dehumanizing the target of abortion violence quiets the conscience and makes the killing easier.  This is why persistent attempts are made to deny the humanity and personhood of the pre-born human life.
