I have mixed feelings about this. Sure, they should go ahead and recite the prayers, but this is not a case of innocent possession. The abortionists are deliberately and intentionally doing the devil’s work. I believe an exorcism can not be successful when the individual desires the possession.
Good point, but some are actually ignorant, i.e. the non-medical help.
Regardless, I believe that this is akin to expelling demons from a home.
From the old Catholic Encyclopedia:
According to Catholic belief demons or fallen angels retain their natural power, as intelligent beings, of acting on the material universe, and using material objects and directing material forces for their own wicked ends; and this power, which is in itself limited, and is subject, of course, to the control of Divine providence, is believed to have been allowed a wider scope for its activity in the consequence of the sin of mankind.
Hence places and things as well as persons are naturally liable to diabolical infestation, within limits permitted by God, and exorcism in regard to them is nothing more that a prayer to God, in the name of His Church, to restrain this diabolical power supernaturally, and a profession of faith in His willingness to do so on behalf of His servants on earth.
The chief things formally exorcised in blessing are water, salt, oil, and these in turn are used in personal exorcisms, and in blessing or consecrating places (e.g. churches) and objects (e.g. altars, sacred vessels, church bells) connected with public worship, or intended for private devotion. Holy water, the sacramental with which the ordinary faithful are most familiar, is a mixture of exorcised water and exorcised salt; and in the prayer of blessing, God is besought to endow these material elements with a supernatural power of protecting those who use them with faith against all the attacks of the devil. This kind of indirect exorcism by means of exorcised objects is an extension of the original idea; but it introduces no new principle, and it has been used in the Church from the earliest ages.
That is true, but this is an exorcism of locality.
The person may not have full knowledge or full consent in this "permission" --- i.e. a kid could be drunk and say "OK, I'm on Satan's team" or just half-jokingly perform some stupid act of sacrilege --- but basically, Satan cannot overpower and possess a person completely against their will.
Satan can "oppress" or "attack" an innocent unwilling person, but he does not have the power to "possess" an innocent unwilling person.
