Theories of Punishment are a controversial and frequently debated topic. It is needless to mention that satisfactory justification and practical application of theories of punishment is one of the most important and complex problems in ethics. But till nowadays this problem remains unresolved although efforts have been going on to have a generally accepted solution to this problem. So it is a time that we must prepare ourselves for the change by changing and improving the understanding of morals value systems in general and the nature of human mind and society in context of the crime, criminal, penalty e.g., to take first step towards an acceptable perspective on these important issues and to take the further steps towards the beginning of a new human civilization. Punishment can be used as a method of reducing the incidence of criminal behavior either by deterring the potential offenders or by preventing them from repeating the offence or by reforming them into law-abiding citizens. Theories of punishment, contain generally policies regarding theories of punishment namely: Retributive ( It makes criminals suffer for what they have done wrong ), Deterrent ( The aim of punishment is to stop people from committing crimes ), and Reformative ( The object of punishment should be the reform of the offender ). The subject has been discussed by a number of philosophers- A. Macdonald, Michel Foucault, I. Ehrlich, Friedrich Nietzsche, I. Kant, A. Posner Richard, C. D. Broad, T. Hobbes, R.M. Bohm, H.L. A. Hart, Hugo Adam Bedu, Jeremy Bentham and many others.
