Sometimes taking something and preserving it is not a bad thing. Anyone recall https://en.wikipedia.org/wiki/Buddhas_of_Bamiyan?

I'm pretty sure thousand or 10 of thousand of Egyptian artifacts were looted, probably quite often by Egyptians.

Take at look at many regions of the African continent. When ethnic groups or even groups they perceived themselves different would wipe out tribes or societies, artifacts were taken or destroyed.
