That is definitly true. It is not an easy question. I am not saying that all they did was good. But they have done some remarkable work.

I think this is a really human phenomena. Almost all cultures and people worked this way. The Greeks, the Romans, the Franks, the French, the Brits, the US, the Germans and also the Eastern empires, as well as the conquest by Mohammed...
So it seems like something very human to do.

Still, I think that the good things can be appreciated.

Have a great day!
