Yeah, I've noticed this hypocrisy and inconsistent logic by most people in society as well. In the past, I would have been more vocal and argued against it, but nowadays suffering a lot and wanting to exit sooner than later (been like that but more intense in the past year or two). I would attribute this kind of thinking and logic by society as a fallacy, the fallacy of a 'just world' (or simply, 'Just world fallacy') and then also the notion that people don't want to face the (inconvenient) truth.
@Forever Sleep made great points as well, especially about the investments made into a person. Regarding that, I would add that this 'investment' sadly is an non-consensual investment that (collective) society imposed on the individual as no sentient being has ever willingly consented to this unwritten contract or investment, but simply just being conceived, they were imposed that from birth. This includes one's parents nurturing and educating them, teaching them society's norms, rules, and laws, etc., and through the indoctrination of school and society itself. That isn't to say that there aren't people who are happy with that, but for those who never wanted to be, but were forced into it, yeah it's basically non-consensual investment. While people may argue that "well if everyone thought that way society would collapse!" but the argument against that would be "perhaps, it's a sign of a broken and messed up society, instead of the individual(s)? and also that the individual(s) has had enough self-realization and awareness to realize the bullshit of sentience. Finally, yes, the last sentence made sense and even if they (subconsciously) believe that, they wouldn't really vocalize or openly admit it (for obvious reasons). So in short, yeah the collective members of society may be aware, but are just unwilling to admit it openly.
