Why rape cases are on the rise all over the world?

The issue of rape is all about social and cultural in nature. Think of what illegal drugs can do to the mind of a person such that an addict would behave strangely as to rape and kill with no purpose at all. In some countries like the Middle East, the root cause is the deprivation. Men are not allowed to see a naked woman and the women there are fully wrapped including the face. So that deprivation adds to the hidden desire and pent up emotion of the men such that they commit rape when they couldn't control themselves anymore.
