False mercy

"Often disguised by the name 'mercy killing,' euthanasia is a form of homicide. No person has a right to take his own life, and no one has the right to take the life of any innocent person.

"In euthanasia, the ill or elderly are killed, by action or omission, out of a misplaced sense of compassion. But true compassion cannot include intentionally doing something intrinsically evil to another person. Like abortion, euthanasia violates the commandment 'You shall not murder.'"
