Abortion is the death of a child, a life which will never see the light of life.
There is a story in the Christian Bible, the Gospel of Matthew, which tells a story story of innocence lost to the same fullness.
After Jesus was born in Bethlehem, Herod slaughtered the innocent children in an effort to eradicate the King Herod saw as a threat. Herod missed killing Jesus, and you know the rest of the story. To this day, Herod is widely condemned for this atrocity.
Today in the USA there is a similar slaughter. More than one million innocents are slaughter every year because they are perceived as a threat to the "mother's" lifestyle. Modern people have even less justification than Herod: Herod was going insane; moderns kill children for convenience.
Abortion is legal, but it is wrong.
