Question

Explain the saying the "end justify the means" when you chose to save the lives of many than the life of one person.

Answer 1

End justify the means   

The phrase “the end justifies the means” is used to suggest that any activity, whether or not that activity could be considered ethically or morally bad, is worth it so long as a desired end result is achieved. Examples of this include cheating at sports in order to win a game, or lying during an election cycle so to get elected.
The origins of the phrase go back to consequentialism. Consequentialism is a type of normative ethical theory. In its purest form, consequentialism holds that the moral quality of an action is completely determined by its consequences; thus, according to consequentialist theory, the end justifies the means in all circumstances.
Of course, for most of us this theory is difficult to square with our desire to get along with, and care for, other people; especially those within our immediate family or friend group. That said, there are plenty of modern-day and historical examples, several of which we will touch upon below, in which this moral pull is ignored, and the ends of bad behavior win out.

Examples of the End Justifying the Means
Whether you agree or disagree with the below examples, they all represent how “the end justifies the means” thinking can drive human nature, for better or worse:

 Lying on a resume to get a job: In your mind, lying (or inflating the truth) on your resume may be justified if it helps you land the job of your dreams.
 Lying on a first date: First dates are awkward, and if you want a first date to turn into a second, the idea of lying to impress the person across the table from you may seem to be a small price to pay to get a second chance to impress.
