When people say things like "right" or "wrong" in these situations, they're referring to their own sensibilities.
As weird as it may be for people to wrap their head around, there's no indication that any absolute right and wrong, or good and evil exist. In absence of it, morality is subjective, and "right and wrong" are going to be left up to individuals to decide.
That being said, culture and upbringing have a lot to do with putting people in a similar location on pretty close to the same page. Sure, you'll end up with some disagreements and you'll even end up with people going against things they'd nominally describe as "moral", but that doesn't mean that the system doesn't work, by and large.
Or, to put it another way: society exists (given), and we by and large find a way to coexist (given). There's no proof objective morality exists, let alone is required for such a system to work.
