"So foolish was I, and ignorant: I was as a beast before thee." Psalm 73:22
The Bible says that in the last days, men will be without "natural affection" (II Timothy 3:3). It is only natural to have love & affection for that which has come from your own loins and is part of you, your offspring. How much more unnatural can one get than to condone & champion the right to kill your own children?
In these days, people have more affinity for the "beasts of the field" than for their own humankind because man's vile lusts have degraded him to the point where he identifies more with beasts than with those who were created to bear the image of Almighty God. Support for abortion in any way is simply the evidence that man has devolved into that which is lower than a beast.
"I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts." Ecclesiastes 3:18
