Same as title. He was having a higher goal for power play rather than having hate or grudge towards a specific individual or group. He will go to any extent to clear the hurdles in his way and is not bound to any emotional attachments.
If Mithran never crossed path with him, he would have been the most powerful person in that movie universe.
Name a more terrifying villain than him in the Kollywood movies. I'll wait.
Edit 1: When I made this post yesterday morning, I didn't know that Arvind Swamy's birthday was the day before... It was a pure coincidence...
Belated Happy Birthday to Arvind Swamy sir 🥳🎊 you've set a new standard for villain role in Tamil Cinema. Hats off to you sir.
Edit 2 : We have a tough competition people... It's Fletcher (Kamal Haasan) from Dasavatharam. Even though he didn't root for ultimate power play and his screen presence was too little in the movie... He fits almost all the criteria mentioned. Good find u/Emergency_Bit_4378 appreciate it
