It's actually a fascinating experience being in the presence of a narcissist for a while. It truly is a different kernel/OS that their mind is running. But exactly -- everyone in such a situation does and will reach this conclusion eventually.

I don't find it fascinating, they're actually quite simplistic, you'll find that they see the world through the eyes of a selfish toddler, where they are perfect, everything is about them and anything they don't like is everyone else's fault. They'll act like the fact that their actions may have consequences that they don't like is somehow the gravest injustice in the world. It's both incredibly boring and exhausting at the same time.

This is what I would do too. Keep them as far away as possible.

Learned this lesson the hard way. The only way to win at this game is to not play at all.
