Question

do you think that brainless and unsuspecting nightingale was her self responsible for her downfall and death?

Answer 1

yes! because he herself was becoming fool. She thinks that the frog has done mastery in singing. She lacks self confidence. She was unable to think that many creatures have come to listen her song only, this meant that she is a good singer.

Answer 2

Yes, I think that the nightingale was her self-responsible for her downfall and death as she was not having confidence in her self that she was a good singer and due to this she easily got caught into frog's plan and died.
