And a K-Mart salesperson does not have the right to refuse to sell you ammunition to prevent you from killing someone?

If K-Mart knew you would use the ammo to go murder someone, then they have a moral duty not to sell it to you. However, they should not be legally prevented from doing so nor should they be held liable if you go kill your wife.

It's only because of guys like John Edwards that a company can be sued for selling a legal product that is later used illegally.

If K-Mart the pharmacist knew you would use the ammo prescription to go murder someone commit an act that violated their Hippocratic Oath, then they have a moral duty not to sell give it (back) to you.
