Oh, I'm very sorry. I just always liked abstract questions

.
Anyway, let me try traditional moral dilemmas. Ahem,
1. You are on a sinking ship. As you rush to a life raft, you see that someone has beaten you to it and is getting ready to set off. All the other ones have left. You have a gun. The raft is only large enough for one family (Yes, you both have families, the same size). Do you shoot him and the other family so that you and your family can get the life raft? Or do you accept defeat and let them escape. Oh, and the boat was over a thermal phenomena that attracted hundreds of sharks that will eat anyone bleeding who enters the water, and you are all bleeding.
2. Your plane crash lands in a place with no modern technology. You aren't MacGyver. A tribe is kind enough to take you in, as you are injured. As you heal, you find out that the area is in a state of constant warfare for survival between competing tribes. You can't communicate with the other tribes, and can barely do so with this one. Being male (For the purposes of this situation, lets say you are), they arm you and take you with them on their next attack. Will you steal, rape, pillage with the tribe to stay alive? Or would you decline and lose the relationship with the only people you know, facing certain lonely death?
3. You are with the Government, and have uncovered a terrorist plot to blow up an important, and very tall, building just in time. The building is being evacuated and on the top floor you catch a terrorist just as he activates the bomb. It is on a timer, and the correct password will deactivate it. You can't move it and there isn't enough time for the bomb squad or escape from the building, as the building is very tall and the elevators are down, and the bomb is huge. Oh, and the windows don't open, and a jump would be fatal. And the roof is a spire, so no helicopter. The terrorist isn't talking. Do you go like Jack Bauer and try to torture the password out of him in the time you have left? Or do you call your spouse and or significant other before you die?
