You can care about other people, but there's nothing like experiencing a problem first-hand. It's a level of selflessness that most people don't ever realize, because it goes against human nature. If a flight loses cabin pressure, you need to put on your own oxygen mask before someone else's. Not that you don't care for other people, but if you don't care for yourself first, you will literally be unable to help others.
