Well, in my faith, we believe that the more you think about death, the better a person it makes you.
you may be asking, well, how is that so? for several reasons.
1. we believe that there is one god who gave us instructions on how to live a good life, heaven and hell
2. we believe that we are acountable for EVERY single actions( yes, even when you stole that glance when no one was looking)

so if we are constantly thinking about death, then that means that we will constantly be thinking about our accountability, which in turn will always thinking about how to do good and prevent evil.

So, often remember the Killer of Desires(death), and you will be less inclined to follow the evil of the soul.

That is what I believe in anyways.
