Lust of the flesh and coveting the pleasures of life. Taking what you can in a selfish way, over indulging without remorse. The vices named in the seven deadly sins are lauded as fatal, in truth there is a greater sin still, the one of omission will often lead to hell. Refusing to show mercy when ever you can. Helping out a stranger that is in need of a hand. So the next time you worry about mortal vice, consider what you didn't do that can affect your afterlife.
