One of the disasters that befalls a person, and a society, when they are enslaved to their own nafs, is that they will divorce purpose and function from sensation and enjoyment. In other words, what feels good, is good. Even if it carried no benefit beyond sensual gratification.
This is why there is “junk food”. This is why so many of us pass our time with trivial, silly things, like games and comedy programs, watching sports, and so on. And, yes, this is why something like homosexuality is becoming an acceptable behavior.
We have forgotten the function of food, the function of time,the function of marriage and sexual intercourse. They have all become matters defined exclusively by the sensation we get from them, rather than by their purpose.
You eat food for its taste instead of its nutrition. You spend you time in ways that will make it pass quickly and pleasantly, instead of productively. You engage in intimacy and sexual relationships exclusively for enjoyment, instead of to bring forth children and build families. Enjoyment and gratification have superseded purpose and function. And this leaves you ultimately in a state of extreme loss.
You food makes you fat and weak, your pass-times devour your life and leave you with no accomplishments, your sexual behavior leaves you with no heirs. You live a life of sporadic, momentary, flashes of pleasure, but with no purpose
