does punishment deter crime and why

2 answers

Punishment deters some crime because rational people avoid painful situations.

However, many criminals are not rational.
If the punishment is certain and immediate, it will definitely deter crime. However, that is not the situation in real life.

Some crimes are not discovered until much after they are committed. Even when discovered, not all are solved. If the criminal is charged with the crime, s/he has to be tried, found guilty and sentenced. If the punishment is given, it is a great time after the crime is committed.

For some criminals, they see their problem as being caught rather than committing the crime.

As Ms. Sue indicates, crimes of passion are definitely not rational.
