The way it is

Joseph Gordon-Levitt, "The Walk"

Maybe we all have in us a secret pond where evil and ugly things germinate and grow strong. But this culture is fenced, and the swimming brood climbs up only to fall back. Might it not be that in the dark ponds of some men the evil grows strong enough to wriggle over the fence and swim free? Would not such a man be our monster, and we are not related to him in our hidden water?  It would be absurd if we did not understand both angels and devils, since we invented them."  ―John Steinbeck, East of Eden
