Many that live deserve death. And some that die deserve life. Can you give it to them? Then do not be too eager to deal out death in judgment. For even the very wise cannot see all ends.
The Fellowship of the Ring, by JRR Tolkien
It is ludicrous to simplify civilizations to black and white, right and wrong, good and bad, 0’s and 1’s. We are all humans, with traditions, and customs, philosophies and opinions. The more one learns about others, the more we will learn about ourselves. Understanding leads to open-mindedness that leads to acceptance.
