This is a nice valid point that you have raised. I would like to dwell on it more and realise the whole sequence of incidents leading to the crime and its incidence.
Society at large has not been able to identify the purpose and need of there being men and women in the human race. The education and culture is teaching men something basically wrong.
The whole thought that punishing a crime would deter others from doing it can be questioned. What does a man gain by doing such acts is at the root cause of such action.
Where and how these thoughts come into the imagination of men needs to be identified. If only we could educate men as to what ejaculation achieves and the biological need for such an arrangement.
If men understood what it was to have sex with a woman and what is the use of such an activity. Wild imaginations and fantasy theories are baseless and reside in the mind of the perporator of the crime. Having a mechanism of validating and verifying search stupid thoughts need to be made available to the men having these thoughts.
If modern education can include a proper and systematic approach about sex its use and prevent imaginary satisfactions future generations would not have to bother about either rapes or their punishments.
I have put together a small ppt about human beings and would love if you can critically review and help me improve it as well as spread to your contacts to reach more people.
Thanks and regards,
