I don’t care what theologians think, because the Bible is clear enough on the matter. All men are guilty in the eyes of God (unless they have obtained grace though Christ), so unless you want to argue that infants in the womb are not men, then they must be guilty as well.
When God judged Sodom and Gomorrah, Abraham “haggled” with God to spare the cities, and God said He would spare it if even ten righteous men could be found in them. Now, I think one could find 10 pregnant women at any time, in any city. So it would have been an easy matter to get the cities spared if infants in the womb are innocent, but obviously that is not the case, for the cities were destroyed.
You had better care what theologians think. The Bible is clear on many things and theologians make sense of what is not clear, based upon context. Sodom was destroyed by their degenerative sin, specifically sodomy, which was ingrained in youth. The people were corrupt to their essence, as were the Amalokites, Jebusites, etc. those who worshiped Moleck. Further, the Old Testament was about the journey of Israel, not salvation for mankind.
When God came in the flesh He led us to another course, that of bringing in people not of the Hebrew line, not from the House of Israel. And thank God for it or we would be lost. Christ condemned those who would harm children (Matthew 18:6). Though His words can be interpreted in a few different ways, we as His children are charged with their protection.
God is not malicious, nor is He uncaring. He delays His return so that the entire number of saved can be counted.
