"the safety of the rescuer is of higher priority than the safety of the victim. Always."
To me this quote means you can't put someone in danger to save another. Many times when I'm watching Tv I see that quote in action but most of the time it some one saying that to a cop and they never listen, they put themselves in the line of danger because they care. They care about whether this person will get to live a long happy life with their family. To me the reason you get a job in law enforcement or as a Fireman is because you want to help people and I personally than them for the service they have done for our country.
Although it does make sense that the rescuers health be taken into full perspective. you never know if the person you rescue is going to survive any way and if it put the rescuer at high risk it really would be for nothing, the morality of it though I think makes it worth while instead of having that on your shoulders you could know you tried which is almost as important as saving someone.
In the book Anna and Kate's father is a Fireman and he goes out and he saves peoples lives. In the end of the book Anna becomes brain dead in a car accident and they give her kidney to Kate which saved her life.
In conclusion......
You should always try to help someone.
