Debates about whether to punish behaviors are debates about whether a decrease in frequency of the behavior is desired.

Whether a decrease in the frequency of the behavior is desired is only one piece of the debate. Other important pieces (from a consequentialist perspective) include how effective the punishment will be, how costly it will be to implement the punishment and what the side effects will be. Even if, for example, society collectively decides that if fewer women dressed like sluts there would be fewer rapes, it does not immediately follow that dressing that way should be a punishable offense.
