What worked to attract humans to the worship of a particular false god in the past still works and the demonic power behind that false god still wants to have humans blaspheme God in the same way. For generations, "the right people", who had money and power always knew who would quietly perform an abortion. The only difference now is that it's done openly and bragged about by those who want to show their loyalty to those with power and to prove they'll do whatever the powerful ask of them in return for acceptance.
It's become a right of passage to prove loyalty to power in this life for the Antichrist crowd. Someone has to have already elevated themselves to the position of supreme authority and accepted that they can set their own standards of right and wrong before they ever get to the point of having an abortion. Some percentage of those who have an abortion may be cajoled and pressured into it, but the majority of folks who have had an abortion were sure that they were only responsible to their own Self rather than to God long before they ever got to the point of an abortion.
The demonic power behind Moloch hasn't gone away, it just employs a different marketing techniques to convince people to sacrifice their children in exchange for power and, "freedom". The slaughter of infants makes the parents murders the creation of murders who defy God is what Moloch stands for. When a nation ceases to be a Christian nation the restraints on powers like Moloch are lessened as punishment for turning away from Christ. Ever since the leftists from the beat" generation become the majority among college professors, the whole academic machinery of the country has focused on turning everyone possible away from Christ toward hedonism and a denial that there is a God other than the Self. Even a great many churches that claim they're Christian churches now preach a message focused on this physical life and self-improvement while teaching that the spirit is primarily a tool to improve the material circumstances of this life rather than something to be nurtured by service to Christ in preperation for life everlasting with Christ.
Wherever the the Self is enshrined Christ is dethroned and no longer considered to be God Almighty. Whether it's an open worship of Self marketed by the mass media or the subtle and more common deification of Self as the final authority in all matters of faith and morals, it amounts to the same thing, the enthronement of and worship of Self rather than the taking up your cross and following Christ.
