“An avidity to punish is always dangerous to liberty. It leads men to stretch, to misinterpret, and to misapply even the best of laws. He that would make his own liberty secure must guard even his enemy from oppression; for if he violates this duty he establishes a precedent that will reach to himself.”
-Thomas Paine

It cannot be explained away as a necessary evil. It is merely evil creeping into soul of a nation.
