I don't know if you've watched anyone die but it isn't "fun" for most people (either the watching or the dying). Many people are there with their parents when they pass, or with grandparents or loved ones struck down by accident or disease. So in general I think everyone will likely watch as at least one other person they know and care about dies.

When that happens, you may find yourself sharing the dying person's pain, and that is a heavy burden. When I am listening to, or reading about, the death of someone. I wish for them an an easy passing, with as little pain and suffering as possible, for both them and their families and loved ones, because I know from my own experience how painful it is to watch someone die and be unable to help them. So for me, the living, it makes a huge difference if the person died doing something they loved (and thus were likely experiencing joy and satisfaction at the end) then knowing someone died slowly, painfully, and inevitably spending hours, perhaps days or weeks, moving toward their own demise.
