I appreciate your answers but in response, I do have a son who will be turning 4 and like yourselves I would do anything in my power to help him. These questions are hypothetical of course and ask you to reply in a manner in which you deem correct, any input from me {or anyone else for that matter} would scue the results or purpose of these types of exercises.
Such as: You are able to help some people, but unfortunately you can only do so by harming other people. The number of people harmed will always be 10 percent of those helped. When considering whether it is morally justified to help does the actual number of people involved make any difference? For example, does it make a difference if you are helping ten people by harming one person rather than helping 100,000 people by harming 10,000 people?
