Sri. HRHK, Greetings.
method may be adharmic in valli vadham but vadham was dharmic.
I fail to understand how vadham, the purpose can be dharmic. Let us look at the situation very closely. What was the reason for enmity between Vali and Sukreeva?
Mayaavi challenged Vali. At that time Vali was the king. Vali got annoyed by Mayaavi, set out to rearrange his face. Sukrive initially asked Vali to ignore Mayaavi, but didn't succeed, folowed Vali. Mayaavi went in a cave; Vali asked Sukreeva to stand guard outside the cave and went in on his own. The fight went on for very very long time. After one year, Sukriva assumed vali was dead and left the cave; before leaving, covered the cave entrance with a huge boulder. On return to Kishkinda, he got himself crowned as the king; took over Vali's wife Tara. ( This is the account as per Valmiki Ramayana). vali came back.
Sukreevan didnot stand guard as requested by Vali until he returned. He not only left post, but also Covered the entrance with a boulder. To make the matters worse, he crowned himself as the king of Kishkinda. Personal insult was, Sukreeva also took Tara for himself. I would be very much interested to know how sukreeva was just? Why would anyone support a beast like Sukreeva? Didn't sukreeva back stab Vali? Sukreeva knew Vali would smash him into pulp; that's why He bowed to vali on his return. but his actions say otherwise.
So, what was wrong if Vali wanted to beat Sukreeva into total submission? Don't you think Sukreeva asked forthe trouble?
Rama supporting Sukreeva was not justified at all. Rama knew the story before promising Sukreeva of his help. Sorry; neither the cause for Vali vadham was justified nor the method was dharmic. Rama was hailed as a "Purushothaman"; Vali vadham was not worthy for him. ( Don't get me wrong. I was a Sundara Kanda Paarayani. Could recite the whole Ramayana one of these days... but, Rama was wrong).
traitor ? common not from you i expect this . vibhishanar for his knowledge and tapas he was respected everywhere he goes, he is not indebted to ravana like karna to duryodhana.
I am sorry to disappoint you, Sir. Duryodhana crowned Karna as the king of Anga. There by, Karna became equal to Duryodhana. Karna had the gratitude. Fate had it, had Duryodhana knew Karna was the eldest of the Pandavas, chances are he would have crowned Karna as the emperor of Kuru dynasty... he had so much respect for him ( from what Vyasa narrates). Karna was free to do what he liked .. he donated kavacha kundalas; he promised to use Nagastra only once; he promised not to engage with any of the Pandavas except Arjuna... he did not have to consult Duryodhana before making such concessions.
O the other hand, Vibishana was the minister. He had obligation to serve the crown. If he was really loyal to the crown, he should have stayed with the crown to the end. But he did not. Secondly, Ravana washis brother. He left Ravana at the time of need. Granted Ravana was not the pure driven snow; but that doesn't justify Vibishna's crossing over. Thirdly, Vibishana alerted Rama about Ravana's army's strength and weaknesses. That was getting low. Can't get lower than that. At the end of it, Vibishana accepted Sri Lanka's crown. Sorry Sir, I see Vibishana as a traitor... a cheap traitor at that.
Cheers!
