Poverty is a state or condition in which a person or community lacks the financial resources and essentials for a minimum standard of living
Villagers suffering from poverty is a thing but judging from the lack of rags on the girl, the fact that the guy is able to become an adventurer (too poor = no money for initial investment such as weapons), the amount of vegetables, shops
"running out of medicine" (meant supply < money), etc. They have "sufficient" wealth for clothes, house, food, and medicine with the medicine running out before their cash because of the epidemic. From this we can judge that the villagers aren't "suffering from poverty".
At the very least, they are not in a situation where they desperately need money. On the other hand, there was an epidemic where the whole village was pretty much bedridden. Having a few extra miracle cures on hand is definitely better. So yes, the mother has short sighted greed.
Basically, if everyone in the village is sick from a very contagious disease and you sell your ONLY REMAINING MEDICINE for money (which you obviously can't use to buy more medicine) then you will just end up as a
rich corpse.
@ravidya I know, its pretty scary that the number of bloodthirsty individuals we have on Mangadex are increasing. Not only do they suggest killing children, they seem to suggest genocide at the smallest incidence.
