I just watched a Harvard course:
which starts with:
If you had to choose between (1) killing one person to save the lives of five others and (2) doing nothing even though you knew that five people would die right before your eyes if you did nothing—what would you do? What would be the right thing to do?
If you have time and you are interested, please watch all the examples from video, especially the last real one and bring your arguments to justify one opinion or another.
