Raavan was popular but for few years, so have been all evil

Raavan was popular and respected king for a FEW YEARS for being most educated, most powerful ruler of a large kingdom he commanded during his time. However, for next thousands of years he is still one of the most hated human of Hindu mythology worthy of being burnt every year symbolising that hatred. So was Hitler who too must have been awesome ruler for Germans for a FEW YEARS giving them pride of letting them dream to rule the world once. Now later, he, for decades, has been confined to dustbin of hatred and is considered most evil ruler ever to have existed in entire history and would probably continue to be hated and abhorred for centuries. Volumes of books and literature continue be created to amplify that hatred over and over again and none to celebrate the FEW YEARS of their ephemeral glory they enjoyed.

History teaches us good lesson that there is not a single example of EVIL continuing to find place of respect and adulation for more than a FEW YEARS. Evil would ride success for limited time only. They would be soon trashed into hell of abomination and contempt which would continue for millenniums. 

No one survived this repeatedly proven historical observation. Hitler, Idi Amin, Pol Pot, Saddam, Mussolini, Stalin, Raavan, Kans, Hrinaykashypu,  would never resurrect their lost glory ever again and would be hated till end. Let this be teaching and good hope for us.

Raavan by the way was good Hindu.
