Sorry for the rambling nature of my post, but the mood took me.
I'm not sure what I'd say about the ethics of couch potatoes.
They don't fit the mold of 'traditionally good ethics, that most people I know in person have.
. . . If one is not 'good, is one 'evil. . .
I think I'd rather say neutral, though certainly to many good people, evil is the absence of good.
Some people's ethics are self serving,
“Not at all. One man cannot wrong another man. He can only wrong himself. As I see it, I do wrong always when I consider the interests of others. Don’t you see? How can two particles of the yeast wrong each other by striving to devour each other? It is their inborn heritage to strive to devour, and to strive not to be devoured. When they depart from this they sin.” - Wolf Larsen
Though that character sounds a bit of traditionally recognized evil I suppose.
If you're looking for a chuckle,
The Devil's Dilemma
I'm reminded a bit of the Eloi, in the piece of fiction, The Time Machine.
In the story, a man creates a time machine and ends up traveling to the far future, where it seems humanity has undergone an extreme apocalypses.
The great cities, societies, and learning, all fallen and crumbled. To dust much, and what left, overgrown.
He 'does find two groups of people though, one of which was the 'Eloi.
The Eloi live a simple communal life, adorn themselves with flowers, dance, and sing in the sun.
But are lazy, weak, apathetic, to the point they don't even save one of their own from drowning in a river, an Eloi named Weena. Instead that task falls to the time traveling protagonist.
And it's that apathetic angle I want to focus on for them, but before that, there 'was another people the time traveler found.
Those humans who escaped underground during the apocalypse, and yet still retained some of mankind's technology.
In the fiction, The Time Machine, it is the Morlocks who provide food and clothing to the Eloi, yet the Morlocks are also the antagonists of the bit of fiction. For they are cannibals, and prey upon the Eloi when night comes, and they can venture out from the darkness beneath the earth.
And in this debate, I ramble even more disjointedly about inaction.
