If you want my opinion, i think the saying on the last picture is absolutely true. Why? Because i couldn't just sit or stand around and watch someone get hurt or killed. You dont need to know why to save someone, you just do. I know if I were in that situation, i would help out whoever it was. You don't have a sufficent excuse to why you didn't help someone. If I was able to make a choice to help someone, you bet your ass i would.
