You seem to think social sophistication or technological level is the measure of a culture and the primary factors that shape their worldview.
What did I say to gave you that impression?
This is what you said that gave me the impression you think most people, including all Muslim, Asian and non democratic nations don't see life as sacred:
I think you're assuming that saying people don't see life as sacred, means they don't value life. There is a difference. For most of the world, an individual life is important but not sacred.
Count the populations of western country's compared to the rest of the world. Count the number of country's that are actual democracies against the total number of countries. Muslim and Asian populations alone make up more than 80% of the world's population. I'd say that was most of the world.
