I think it was the right decision because no one can imagine life in someone' captivity. Freedom is more valuable thing than life. Chandni could have gone back to her small hut of Abbu and saved her life but she chose to ** with the wolf instead, to attain her freedom. She did not like a coward. She fought with courage and bravery to get what she wanted in her life. She might have lived longer in the captivity but she everyday and hated imprisonment. She fought with the wolf and told herself that "success or **** is a matter of luck or chance." So, she took the right decision afterall.
