I would argue it's really more of a want.. growing up my father was a heroin junkie.. wasn't around much.. the relationship was never one where he wasn't allowed to see me or my sister.. but he sure wasn't around... Eh, idk.. father's aren't a requirement, ask anyone being raised by lesbian mother's. ^>^ idk... Feels wrong saying a father is needed... No one "role" is so vital as community.... And anyone can fill in as life advisor, because thats what already happens. Look at children raised racist by their parents, is this father's view the only one? No, society will correct the behavior that's undesired in individuals... Despite fatherly love..
