All of the above is to say, western morality is not all good (nor is it all bad), but the same goes for all the rest. To know more about further examples, that is an ignorance you need to work on personally to cure. Travel outside of the West & read more history. When travelling, culture shock is a real thing, it's striking to learn that others in the world actually think fundamentally differently, they have different values, and in some cases it's even a good thing (and sometimes not, but the fact it's different, it helps break the mold of your own experiences).
