Raising a kid for over a decade before they’re biologically mature is actually pretty long term. Granted, they were probably able to contribute to a hunt before puberty so maybe my points not so sharp. But humans are clearly tasked with survival for decades. Modern society being able to invent scenarios basic human logic fails is probably more a reflection of poor design or lack of accountability somewhere. Ie the periodic learning that things that seemed good were poisonous (lead paint, asbestos) is more about lack of perfect knowledge and thus unforeseeable consequences. Or outright malignant intent. Ok so definitely the capacity for one human to decide a slight increase in some metric is a fine reason to lie/cheat/steal/kill another human is definitely a bug. There are species which don’t kill one another.
