People of European descent in this time brought some amazing things to the world from art, engineering, math and science, but also massive-scale earth destroying industrialisation and a military-industrial complex.
Colonialism was also pretty terrible, but it gave everyone around the world soap in a way too so there's that. 
Aka, Faustian. (The ancient greeks and romans are too societally different to be considered the same as the current European times from the year ~1000 to our contemporary age. and later American too before its death). 
They will just transform societally and culturally. Hopefully without as many theological missteps this time.
