There are numerous people who believe that death will end their miseries. Here’s a quote that points out an alternative perspective:

Don’t depend on death to liberate you from your imperfections. You are exactly the same after death as you were before. Nothing changes; you only give up the body. If you are a thief or a liar before death, you don’t become an angel merely by dying. Whatever you have made of yourself thus far, so will you be hereafter. And when you reincarnate, you will bring that same nature with you. To change, you have to make the effort. The world is the place to do it.”

-Paramahansa Yogananda
