Neither of your examples would be considered murder by those doing them. In the case of slavery you can’t murder property.

A murder is specifically an unjustified killing. And as far as I am aware it is universally considered bad. Which makes sense because murder being considered bad is pretty much baked into the definition.

I can’t think of a modern society that does not condemn going into a random person’s house and killing them. Nor any past ones for that matter.

Now in some backwards ass country they might not consider it murder if that random person was homosexual. Or a killing might be justified in the context of a revolution. Or to bring rain. Or when shooting some guy fleeing with your tv in the back.
