Behavior is a result of perspective, it’s all perspective. IMO, abortion is a smaller detail of a bigger issue, so my response is not as scientifically direct.
There are 2 kinds of people. The first perceive they live in a bright world, and because of that environment they believe, have faith and trust people. These people have no question about the future and they have no problem doing everything they can to make sure babies live, no matter the circumstance.
The other kind perceive they live in a dark world. As a result, they fear, they doubt and have a terrible need to control others. Existing in a dark world is their excuse to participate in omnicide.
The world is not dark. The future is not bleak. Tomorrow will be a good day.

The vast increase in suicides is related to spiritual declension of living Christian faith, and smaller families, plus video games. Death is deceivingly promoted as relief, and end of trouble, versus self-murder being by rational persons being the beginning of the far worse "trouble."
The Christian of Biblical evangelical type faith has a purpose in this life, wherein on the horizontal plane, flowing from the vertical relationship with God, the believer can pray to make a positive difference for time and for eternity in the hearts and lives of people that God brings him into contact with, by the grace of God and to His praise.
