Abortion is probably the most telling example, but the issue seems to me to be even broader. It's the ME-culture, the widespread conviction that nothing and nobody should be allowed to stand in the way of an individual's personal happiness. Obviously, David Ludwig believed that. It seems that Matthew Niedere (the boy from Minnesota who murdered his parents) agreed, as did the friends who helped him. And why wouldn't they? Even the churches today preach a doctrine of Self-Fulfillment.
What you are describing is the final destination of the abortion culture: moral nihlism.
In this view, the only thing that constitutes a "wrong" is the thing that you somehow view as an obstacle to your personal happiness/fulfillment, etc.
Once culture internalizes the idea that you can go so far as to kill a helpless human being simply because he is inconvenient for you, it is not a large leap to conclude that any time someone or something is inconvenient to you in any way that you are justified in doing whatever it takes to remove the inconvenience.
You got that right.
I once had a friend who told me he had spent years figuring out the real meaning of the story of Job. (Not the church-taught version in which the meaning is just be patient through life's difficulties.)
He said he eventually concluded that without the story of Job, and the realities it conveys, people would be lining up to follow Christ, not because they loved him and were willing to take whatever came to follow him, but because they viewed being a Christian as in their own immediate (fleshly) self-interest.
IOW, sign up for Christianity---be healthy, wealthy and thin!
As opposed to Jesus who said, Do you think you're *really willing* to go where I'm going? IOW, have you counted *the cost*?
