In the real world, cold calculating brutality survives over emotion, compassion and morality. Think of the Spartans.
Tha Chinese are absolutely ruthless and gaining more world power every day.
Yes, think of them. Where are they now?
I guess you forgot who won WW2, and the Cold War then.
Compassion, Morality, Resolve and the Ingenuity of Free People trump Cold Calculating Brutality any day of the week.
But without Resolve, Freedom is doomed.
You are wrong. The Spartans were defeated by the Athenians, the first Democrats. The Nazis, very cold, calculating, ruthless, also defeated by the free world of democracies. The Soviets, likewise.
History would suggest that one cannot social engineer a society that is as strong and prosperous as a society of individuals free to pursue their own individual dreams. Centralized economies and social engineering don't work in the long run and are inefficient even in the short run.
The Spartans died out (well the “true” Spartans, the Spartiates did), like every aristocratic warrior caste. The European nobility has turned over several times likewise, being periodically wiped out in the male lines.
They were brutal but they weren’t realists, they had a non-rational ethic that served them well in achieving power, but it had certain drawbacks with respect to long term survival.
