But ataman, alcoholics are NOT hedonists. I thought you had understood that already ... As a matter of fact, some of those people addicted to drinking, gambling, sex, etc. are depressed and even suicidal and are definitely not enjoying what they are doing - they just cannot stop it.
It's hard to imagine a hedonist being "depressed" and "suicidal".
If one insists upon finding a link between hedonism and morality, one could at best call a TRUE hedonist AMORAL rather than IMMORAL. Maybe, ataman, that's the term you're looking for?
