circumstances except where the life of the mother is TRULY at risk ie when the choice is to save the mother's life, or lose both mother and child.
If one supports the action of abortion, by supporting it's legality and availability to those whose life is not at risk, then one supports an act of evil and becomes a participant in the process.
True repentance, and the Act of Reconciliation (Confession) with the intent to never do so again is the solution (as it is for all sins, but most importantly for those mortal sins which would prevent us from entering into it to heaven with God).
When we die, there is no more do-overs. Our life and actions are done. I hope and pray that none of us dies with mortal sin on our souls. Abortion really is one of those grave mortal sins that has been made easy to rationalize by our present day society.
