Down The Rabbit Hole

What really stood out to me was

           "All the goodness and the heroism will rise up again then be cut down again and rise up. It isn't that the evil thing wins - it never will - but that doesn't mean it dies."

 What really had me think was the part where Steinbeck mentions mechanics of a human species being suicidal. It really set mt brain wheels to turn LOL.....

I went down The Rabbit Hole...
I started to research about how the human species has developed natural defenses against suicide.....
