When a person is in such a high stress situation, his senses aren't working properly. Now having said that, pilots, ship captains are suppose to be the last ones of the boat, if something were to go wrong. But they are trained for the emergencies, your not. What you did under the circumstances is justified, although I'm not familiar with the whole episode. I would say, that if your friend has survived you had a hand in it. After you jumped, the criminals would have panicked, and at that point, they start making mistakes. So get over it, talk to your friend, and think this is another experience in life. And if both of you have survived, it is time for you to rethink your life, and start helping society. Like volunteering and stuff...
