I have…seen many die, but I have never yet seen anyone who regretted at that moment that he had done too much good or who felt happy that he had lead an evil life. The reason is obvious, and you should never forget it, my dear sons. Evil may please momentarily, but it leaves us nothing but remorse. On the contrary, the good we do, not only gladdens us then and there, but also gives us a lifelong feeling of contentment. Which of the two will please us more at the moment of death?
--St. John Bosco
