You should have gratitude for our society because it is the only thing which kept your ancestors from murdering each other.

You should look into Aztec civilisation :)))

I'll make it easier for you:

It is possible that around 20,000 people were sacrificed a year in the Aztec Empire. Special occasions demanded more blood – when a new temple to Huitzilopochtli was dedicated in 1487, an estimated 80,400 people were sacrificed.

PS. I just mentioned 1 civilisation... You should check the rest...
