well possibly the fact that fear and embarrassment or failure fills peoples every day lives. So when people die new people have a chance to live a life and maybe a better and a lot cheerful one. Also lots of people do not get a chance to do things for who knows what. so when people ( normally old people) die, other people have a chance to do more crazy fun things in life. But when bad things happen things get better leaving what is only the most important in life.
