This article makes a very convincing argument for the connection between abortion and arrogance.  Following this line of logic helps us get down to the root of the matter, in fact all the matters that afflict our relationships.  Here is the final paragraph, a gem of clarity and insight:

How would our lives be different if we understood that we are never more important than our spouse? We are never more important than our children? We are never more important than our neighbor or brother? The culture of life — indeed, grace itself — begins with the denial of self, and unless we begin to deny self, we could overturn Roe and still not overcome abortion — much less the sins that separate us from God and man.
