It comes from anger and disappointment towards everyone else; “how did we let this happen and do I now have to suffer an entire life of shit just so they can continue living ‘the dream’”?

So it’s a mindset of “the world is definitely gonna collapse anyway, do I at least get to watch it burn before I die, or am I just here to facilitate the suffering of the next generation?”. Nobody is looking forward to the collapse, but some people honestly don’t mind if it happens sooner so they can say ‘I told you so’.
