I don't see anything wrong in eloping & getting married. She & He both are of marriageable age as per Hindu Marriage Act, and what they have done is as per their will & no one has the right to comment. In how many film Chiranjeevi himself would have done the same. Ask him to count. It would have been a film but how many would have done the same after seeing the film, now the same has happened in his family. So he doesn't need to get shocked or need to be sad.
His brother is also no good. He is himself caught in a bigamy case. Why talk about kidnapping when members in his family are also not good. I don't think I need to elaborate further.
