Let's dive into some cases with ethical dilemma.

You are at your best friend's wedding just an hour before the ceremony is to start. Earlier that day, you came across definitive proof that your best friend's spouse-to-be is having an affair with the best man/maid of honor, and you catch them sneaking out of a room together looking disheveled. If you tell your friend about the affair, their day will be ruined, but you don't want them to marry a cheater. What do you do?

You are an eyewitness to a crime: A man has robbed a bank, but instead of keeping the money for himself, he donates it to a poor orphanage that can now afford to feed, clothe, and care for its children. You know who committed the crime. If you go to the authorities with the information, there's a good chance the money will be returned to the bank, leaving a lot of kids in need. What do you do?

You have a job as network administrator for a company that also employs your best friend's husband. One day, your best friend's spouse sends you a message asking you to release an email from quarantine. This requires you to open the email, at which point you discover that it's correspondence between this person and their secret lover. After releasing the email, you find yourself in a pickle. Your instinct is to tell your best friend about their spouse's infidelities, but divulging the contents of company emails is against company policy and you could lose your job. Once it becomes plain that your best friend found out about their cheating spouse through a company email, all trails will inevitably lead to you as the leak. Do you tell him about the indiscretion?

You've been on a cruise for two days when there's an accident that forces everyone on board to abandon ship. During the evacuation, one of the boats is damaged, leaving it with a hole that fills it with water. You figure that with 10 people in the boat, you can keep the boat afloat by having nine people scoop the filling water out by hand for 10 minutes while the 10th person rests. After that person's 10-minute rest, he or she will get back to work while another person rests, and so on. This should keep the boat from sinking long enough for a rescue team to find you as long as it happens within five hours. You're taking your first brake when you notice your best friend in a sound lifeboat with only nine people in it and he beckons you to swim over and join them so you won't have to keep bailing out water. If you leave the people in the sinking boat, they will only be able to stay afloat for two hours instead of five, decreasing their chance of being rescued, but securing yours. What do you do?

You're involved in a two-car crash on your way to work one morning in which you accidentally hit and kill a pedestrian. As you get out of the car, you are intercepted by a tearful woman who seems to think that she hit and killed the pedestrian. You're not sure why she thinks she hit the person, but she is convinced. There's only you, the woman, and the person you hit on the road; there are no witnesses. You know that whoever is deemed responsible will probably be sent to jail. What do you do?

Your family is vacationing alone on a private stretch of beach with no lifeguard. Your daughter and your niece, both 7, are best friends and eager to get into the water. You caution them to wait until the water calms down, but they defy you and sneak in anyway. You soon hear screams of distress and find them both caught in a strong current. You are the only swimmer strong enough to save them, but you can only save one at a time. Your niece is a very poor swimmer and likely won't make it much longer. Your daughter is a stronger swimmer, but only has a 50% chance of holding on long enough for you to come back for her. Who do you save first?

You are an EMT on the scene of a car crash that involves your spouse and the lover you didn't know s/he had. They are both gravely injured, your spouse's injuries are the worst of them. You can tell it's unlikely s/he will pull through. Meanwhile, his/her lover has a neck wound that will prove fatal if pressure isn't applied soon. Whom do you choose to work on?

The manufacturing cost of the widgets your company makes has dropped by 50%. One of your customers, Sam, tells you he knows this because he is best friends with your company’s VP of production and asks you for a discount on his order. Your boss okays the discount. Your other customer, Sue (who is one of your best friends and knows nothing about the drop in manufacturing costs), places the exact same order for widgets as Sam. Do you offer her a similar discount? Do you tell her about the drop in manufacturing costs?

You are a doctor at a top hospital. You have six gravely ill patients, five of whom are in urgent need of organ transplants. You can't help them, though, because there are no available organs that can be used to save their lives. The sixth patient, however, will die without a particular medicine. If s/he dies, you will be able to save the other five patients by using the organs of patient 6, who is an organ donor. What do you do?
