To protect social interests worthy of protection, states have the right of punishment in order to combat crime in society by drawing up a sophisticated criminal policy that is compatible with the changes that occur in society. Changes may be political, social, or economic. The legal rule is to split the punishment to determine the appropriate penalty and the act violating the law in order to deter the violator, rehabilitate him/her, and return him/her as a useful member in the society. Several factors make the practice of the state's right of punishment a valid way to formulate criminal policy in the state.
