Why were they always stingy and unwilling to share?

" I like to read apocalyptic novels with portable spaces, but I find that those female protagonists are all very stingy. There are obviously a lot of resources in the space, but they are unwilling to take them out. It's fine if you're afraid of being cut into pieces in the early stages, but in the later stages, you have the ability, so why are you still unwilling to take out the resources? Recently, I saw a book that was willing to take out resources. It was called " The Forced Virgin Mary of Doomsday ". I think it's like this. I think it's quite good. I like this female protagonist too. I hope that someone can introduce a few more similar books. I don't wish to be a saint, but I also don't wish to be too selfish. The heavens have given you so many benefits, so it's only right for you to repay them. You don't have a conscience at all. Everyone, tell me if I'm right.
