Moral dilemma

For all 3 cases i justify the killing. The reason that i justify the killing is because it is clearly for the greater goods. In all 3 cases the person who is the sacrifice will die shorty. The kid on the ship is about to die, the Jewish kids are about to be send to the concentration camp and hypothetically i can't live more than a week. It is justify to kill us because it save other people lives without significantly shortening other people lives. They say that i believe in logic and that i would have to make tough decision in the future. I think they are quite accurate because i think i am a man of logic, making decision without too much emotion.

The best field that matches the Plato cave theory is the future. We can never know what the future holds; we can only speculate from the present. Even someone from the future travels back though time, we wouldn't understand what he or she is talking about because it a different world
