Earlier quoted context omitted.
Not OP, but I've met people that seemed to sort of lost their agency and ambition, because their psychedelic insight was that the universe will sort everything out on its own. Though maybe the causality is the other way round here - they were not ambitious in the first place and psychedelic insight helped rationalise that. Also disclaimer: I'm not trying to discourage or encourage people from psychedelics. Personally…
doesn't sound like their "minds were ruined", but rather that they have different priorities than you and that you're narrowminded and judgemental.
Having been loosely affiliated with the Goa/Psytrance scene, I too, have met some individuals who seemed to have "fried" their brains.
If those "different priorities", how you call it, also include being almost dysfunctional and therefore dependent on constant external support, paranoid and frequently incoherent then, yes, it made me judgmental too.
And this isn't even speaking of phenomena like Hallucinogen persisting perception disorder (HPPD)[1].
