Hey its just my view to the tv serial, dont take it so seriously, if you understand it, then you can.
I dont know why did our elders or any one havent ever explained us, what was raavan actualy, and why and how he became like he was. and whats the good things about him.
And also exposes the role of VISHNU, who somewhere made unjustice to those DAITYAs by taking their rule over the lanka and given to the undeserved DEVs. in which SHIV did not supported that act. so it seems just a CHAL to born on earth as RAM and kill RAAVAN and becamed HERO. Where in reality the heros are the Sumali, her daughter Ketsi and the must Raavan.
this is good message to our present and upcomming generations, which is more likly being very western and relies on totaly un-emotional relationship, and living their life without any aim in their life, just leaving it dont know why they born.
