The state has no right to decide what is “moral” or “immoral” for society. Each and every individual through their freedom of conscience is allowed to determine for themselves what a moral act would be as the government has no way of determining that with any certainty.  Moreover, there is no evidence that suggests any link between S&amp;M and propensity or escalation of criminality. Simply because someone enjoys the infliction or the feeling of pain does not mean that they will become a criminal who inflicts pain on other, un-consenting people in the future. Further, it could be argued that allowing people a consensual outlet for such urges reduces the probability that such escalation and criminality will occur.
