Test your own Morality
I thought of this question for months, and still never came up with an answer I am satisfied with:
Presented Situation: Mankind has come up with a time machine that will allow you to travel back in time before the Holocaust began. Your mission is to go back in time and assassinate Hitler, in order to prevent the Holocaust from ever happening. If you kill Hitler, the Holocaust will not happen, and all those lives will be spared
The PROBLEM: The Time Machine will only work once, and you only have enough power and accurate coordinates to travel to the time when Hitler was an infant. You have to kill Hitler when he was 2 years old. This will be your only chance to kill him and prevent the horrible atrocity that is the Holocaust.
Question: Can you do it ? Would you kill the baby Adolf Hitler to prevent the Holocaust from ever happening ? Is killing one infant worth saving millions of lives ?
