Good v/s bad

[Anil]

If someone did anything wrong and is not punished for that, the science of psychology says that people may not think it\\\'s wrong anymore.

this is what i always to think about.why does not god punish a person immediately after he commits a sin so that he will never again commit a sin.That will make every person live a better life with some honesty and moral values.But as you know such things never happen coz god also wants something to entertain himself
