The most horrifying one to me was the number of people who chose to keep their life savings rather than save 4 people.
I’m not justifying it but if they have a spouse and a few kids they might consider their long term survival over the immediate survival of strangers.
Money can be replaced, lives cannot. If you wanna be more self-serving, those 4 people would probably be very grateful for what you did and help you get back on your feet.
