You stayed in the Stone Age?
Modern Rome, Italy, no longer throws people at the lions, because the laws have changed, and then, it wasn't just Rome that made this monstrosity, for example:
The Holy Bible, Daniel, in the lion's den. Daniel chapter 6, in the Babylon of those times, King Darius, ordered that Daniel should be thrown into the pit of the lions, but God frees him.
So, even your countrymen dropped atomic bombs on Hiroshima and Nagasaki, and killed thousands of people. This is worse than lions!
