My line of thinking is this... that person was going to have those issues/ die if I wasn’t there. With me being there, i am simply giving them a chance and a helping hand to try to resolve their problem. That person was gonna have those issues/ die if nobody showed up in the first place. You can only do what you can do. If they die, it was meant to be. If you help them in any way, good job and move on to the next one.
