Legend has it that when God created man, he hung two bags on his body: the first bag was used to contain other people's evil deeds, and the latter bag was used to contain his own evil deeds.
But "when a horse stumbles, God sometimes misses." When He created man, He created him wrongly! That person never uses the bag in front of him to contain other people's evil deeds, but for his own evil deeds. . . . . .
