To claim the right to abortion, infanticide, and euthanasia, and to recognize that right in law, means to attribute to human freedom a perverse and evil significance: that of an absolute power over others and against others. This is the death of true freedom: “Truly, truly, I say to you, every one who commits sin is a slave to sin” (Jn 8:34).

—Pope John Paul II
