Eighth Amendment

"Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted."

The VIII Amendment is a very important one because it establishes that punishment can't be excessive and it should be proportional to the crime committed and the fines and bails can't be large amounts. 

This amendment has been controversial because in the United States the Death Penalty is allowed which could be considered an excessive punishment.

This video discusses what is a cruel or unusual punishment and how that is decided. The constitution doesn't say what is considered a cruel punishment so there has been many talk about this issue. 

Here we can see how a man that steels some money is punished excessively with a fine of 500 million dollars and 300 years in jail.
