Part 1:

The first situation I choose is situation number 1
-I would quite simple contact the police and inform them of the guy's horrible intentions. It's totally unnecesary to do anything else, such as poisening him with poppy seeds. However if the police don't do anything about it, I'de probably resort to poisening him. I would do this because there's no reason to hurt anybody unless you absolutely have to, to save the potentially affected. I'm obligated to protect his potential victims as a citezen. So the consequenses of my actions would be saving those people from harm. It can potentially be wrong because like I said, the police might not take my word for it and fail to act.

The second situation I choose is situation number 4
-I would without hesitation remove one of the man's kidneys. The reason is obviously so I can save the SIX people, whose interest I'm obligated to protect. This was a very easy decision for me. Possible consequenses of my actions would be the man with the vitamin-filled kidney. But if he wants to fight it would be one vs. seven. It might be morally wrong because it was their responsibility to bring their kidney vitamins, and other people shouldn't suffer for their irresponsibility.
