If we remove criminals from society, it wil reduce the crime rates. So, since there are no lawbrakers, the society will be safer. Also, prison is a terrifying place, so potential criminals will be afraid to break the law. So, in conclusion, I think that criminals should be sent to prison.
Corporal punishment can be warranted and due to a criminal. If a criminal did some thing wrong, but not severely wrong, they should be punished, but since prisoners have very little in terms of possessions, they can only be punished by physical means. So, occasionally, prisoners should be punished physically.
Corporal punishment on a criminal would be cruel and unusual punishment. It would also give correction officers and others a way to severely abuse the criminals. Instead of just a minor use of punishment, a corrections officer would be likely to severely beat the criminal which could even lead to the death of the criminal.
