No one has an inherent "right to life." The state grants it and can take it away, like with all "rights."
Ah ha. I chose the title intentionally to see if anyone would challenge me on that assertion. I agree that what we usually think of when discussing "rights" are merely privileges enforced by the state. But let's discuss rights on a more philosophical or fundamental level. If there is no concept of a right to life, can one not rationalize murder? If a person has no right to live, why shouldn't they die?
