"A trolley is coming down a track, and its going to run over and kill five people if it continues. A person standing next to the track can flip a switch and turn the trolley onto a side track where it will kill one but save the five. Most people think thats morally permissible to harm one person when five are saved. Another case is when a nurse comes up to a doctor and says, Doctor, weve got five patients in critical care; each one needs an organ to survive. We do not have time to send out for organs, but a healthy person just walked into the hospital we can take his organs and save the five. Is that OK? No one says yes to that one."

How do you explain this? Are we all driven by a certain moral code to make these deicsions? And, if so, how/when is it developed?

Is morality innate and universal?
