Guilt

Guilt is a punishment not an emotion!

The punishment will take away the guilt. If you commit a sin and try to escape, the byproduct of that action will lead to guilt. The guilt is the punishment that will follow you and keep you occupied. When you experience or see similar events, the trauma you undergo is called guilt.

The guilt is worse than the punishment because you pushed the sin into your bag called subconscious and you drag it till death. The fear of getting caught of the sin is more painful than the punishment. You live through this and the pain of not being able to reveal is called guilt.

Politicians who do corruption and try to protect the money will be suffering in the name of guilt. The pain in saving the corrupted money and taking measures to hide it and never being in a position of spending proudly will create an endless pain in him. The pain he undergoes is not an emotion but a punishment. Hence, we should not punish him for proving his act of corruption. 
Just leave him, let him suffer pain in the name of guilt. 
It is the same as someone who cheated you and walked free in front of you. The presence of you before him is enough for him to suffer guilt rather than smashing him. Once you hit him for his act then he will escape from the guilt because he was punished for his wrong doing to you. Just leave him and let him die on guilt

The guilt is severe punishment than the actual punishment. Normally punishment is given to the body in prison, the Prevention of movement inside prison but still he can breathe freedom coz you can’t touch his soul. He convinces his mind for the act of his corruption or cheating. But if you leave free by not bringing him under the law then he will die in the name of guilt.
