The remedy would be to tell people that have had abortions that they can absolve themselves as guilt for it if they work to prevent others from following in their footsteps. Trying to cover up one's guilt by encouraging others to get stuck in it won't work. It might ameliorate the pain for a little while, but the pain will always come back. Destroying the guilt by acknowledging the wrong of one's past actions and going beyond it will work, and it's the only approach that will.
One of Satan’s most successful lies is telling someone that whatever sin they committed, there is no way God can forgive that...
His Grace is sufficient...
