What I find most annoying about it is that they're perfectly aware that what they're doing is wrong in their moral codex, but they still do it because "it's a once in a lifetime opportunity", "I really, really wanted to" etc etc, yet they're somehow unable to assume that others might feel the same way about their own life and their opportunities.

It looks like the classic NPC-illusion where people think that yes, everybody should totally do whatever is right, but it shouldn't apply to themselves, because they are the player, not just another NPC. They tend to forget that they're NPCs to everyone else.

But I ascribe most of it to them being young. I'm sure if I had been more politically aligned with the mainstream when I was 20, I would've been insufferable as well.
