What about forcing friends to sign the death sentence of their wifes just to test loyalty?
What about sentencing life-long friends to death simply because those friends had some political ambition?

What about confiscating most of the production of ALL peasants, leading to the greatest starvation of the century?
What about sentencing dozens of thousands to death because they voiced some "anti-soviet" opinion?
What about sentencing people to death just because, at some point, they had cordial relations with Trotsky?
