Everything outside seems dangerous. The rooms where we feel safe are defined by the familiar, the faces we know.
The people we don't know could do anything, say anything. We protect ourselves by deciding they are evil.
But the mere thought that there is good and evil creates evil. Because it is the means by which we separate ourselves from the other. Reject the other. Dehumanize the other. Separation -- the delusion that we are not all one -- is what evil is made of.
There is no them. The room that seemed so small it contained just a single life holds everyone.
