If somewthing was worth dying for then you wouldn't have a choice would you?
Fortunatly we live in a country where were not often faced with such circumstances...But the people storming the beaches of Normandy didn't have a choice...But I believe their deaths were worth the price.
If your child were about to be hit by a bus and you had a chance to push him or her out of the way but it meant your certain death...You also wouldn't have a choice...
