Nobody on this thread is defending a rapist...or justifying the act of rape.

Not all the drunk drivers crash their cars but as there would be more chances of an accident, hence, DUI is considered as illegal around the world. Same concept or theory can be applied here as well.

Another example...In Construction field, we've to look after each & every aspect of safety, be it the least chance of an accident. These are just pre-cautionery measures that we consider before starting & during the work...and it helps us having an accident free work.
