I would kill 1 person to save 2. CMV

Assume that the only consequence of killing this one person will be that the other 2 are able to live. Essentially, destroying this one person's life is the means to save the other 2 people. Also, you are the only person who is able to perform this act. All of these three people are not expected to die any time soon and are not suicidal. You can assume they are men of means or not, I personally don't think it matters and that 1 powerful life is never more important than two squalid lives. If you want to debate about that though, go ahead.

I would kill 1 to save 2 because, although I feel it is my duty not to murder people, I feel compelled to kill in this case because it saves more people

edit: assume you don't know much about the three people, and are therefore not responsible for any indirect consequences such as causing more deaths or failing to save more people if you choose to kill the 1 man.

At a very basic level, consider that this means that the one person will kill you to save themselves.  And be quite justified in doing so as *they* are killing *in self defense*. 

To even begin to be logically consistent and morally correct you would have to also be willing to sacrifice yourself to save two people.  If you aren't then you are just playing god.
