That's why it's an apparent good. In reality, objectively, life is a greater good than the pleasure of drinking, since the pleasure of drinking is impossible without life.
It is possible for people to choose the apparent good over even the known objective good. This happens every day, and it's called moral evil or sin.
So, naturally, and pretty logically, you choose the greater good over the lesser one.
The apparent good, not the greater good. Life is the greater good, since pleasure of any kind is altogether impossible without it.
In your value system, however deranged it could be or appear, you will always be entirely logical- you have evolved that way.
Logic is the basis of all reasoning. It doesn't vary from person to person. If it did, interpersonal communication would be impossible.
The only exceptions are accidents, and one could even make the same argument about the involuntary actions [I force you to drink at gunpoint. You do not want or like to drink, but you do not want to die either - and naturally and logically, you choose the lesser evil, aka the greater good, and drink].
This would be logical, contrary to your prior example. I would be choosing the lesser evil --drunkenness over death.
And as for your other post - yep, I saw the pictures. No emotional reaction of any significance on my part.
FYI, you come across as a monster.
Regardless, I wasn't interested in your emotional reaction to the photos but whether or not you regard these infants as human beings.
