Not quite what I’m saying. It goes the other way around: people are morally questionable by nature and this comes out when people have the chance to act without facing consequences.
So the debate essentially boils down to whether you think people are essentially good/bad at heart. That’s something people can reasonably disagree on.
This is actually one of the things I would wish for if I had a magic lamp.
The ability to grant or take away perfect immortality to any living thing.
To be the most intelligent human to ever exist (so far)
The ability to see any point in space and time.
You’re right that it would likely have psychological ramifications (probably end up like Brandon Stark from GOT). But it would be fun for a couple thousand years.
