I would do anything in my power to help.
You don't need to get your hands dirty, all you need to do is hit a few buttons on your phone.
Or if you're not a retard and had CPR/Life saving lessons in school you would know what you'd have to do in order to save them
I would try to help, I've been trained in CPR, even if they died I feel better for knowing the I tried to save them, rather than just watch and let them die as I hope someone else will go to them.
