"In keeping silent about evil, in burying it so deep within us that no sign of it appears on the surface, we are implanting it, and it will rise up a thousand fold in the future. When we neither punish nor reproach evildoers, we are not simply protecting their trivial old age, we are thereby ripping the foundations of justice from beneath new generations."
- Aleksandr I. Solzhenitsyn
I read his books years ago, solzhenitsyn knew the face of evil. Definitely worth a read.
