There are individual sins and there are corporate sins. A woman who has an abortion commits the former; a nation that enshrines her right to do so in its law commits the latter. I leave it to you to weigh which is the greater offense.
From Sinai onward, upon becoming conscious of having personally violated God’s laws, individual Israelites could bring their offerings to the tabernacle or temple all year round to have their transgressions covered over. But Israel’s corporate transgressions also needed a way of being covered over, being arguably more offensive to God than sins any lone Israelite might commit, and therefore more likely to be the source of an outbreak of divine wrath against the entire nation.
