More specifically, the more recent studies analyze non-drinkers in two categories: those who just choose not to drink (generally healthier than even light drinkers), and those who don’t drink because they have serious health conditions incompatible with drinking or people recovering from substance/alcohol abuse issues who (generally much less healthy than light drinkers). By separating those who don’t drink versus those who can’t drink, the studies reverse earlier findings that non-drinkers are less healthy than light drinkers.
I agree. Stated another way, imagine the trolley is headed towards 5 people, and you have the power to pull the lever to divert it to a path where there are no people. Even if someone tied those 5 to the tracks with the intent to kill, your failure to save their lives (at no additional cost to others) is widely regarded by most systems of ethics/morality as a moral failing. Yes, the person who tied the tracks bears blame, but so does the person who could’ve easily saved them but chose to let them die.
