Stories develop over time and they pick up the morality of the time when they are being told. For an analogy, there are speculations that the mythological story about “Helen of Troy” relates to customs of basically… kidnapping women in raids (they were a seafaring culture) at the time Homer was writing.

For a repetition of the pattern, the trojan war itself was fought by people of a culture had already “collapsed,” followed by a dark age and was in the process of rebooting. They were transcribing oral traditions and that’s why we know the Homeric stories today, the writings of the early revivalists. Maybe Homer’s great grandma had a basement full of canned soup and a nice cabin in a strategic location.
