Doing what is right is the ultimate thing to do no matter what it takes and how it makes you feel as a person , if saving someone life who is at the edge of death or been killed and the outcome involved a lot of risk. I will certainly take the risk to save that precious life, so to clearly answer your question I will definately do what is right without weighing the risk or reward involved.

Doing the right thing is more important than any risk or reward @poeticsnake
