As much as I admired bluestar and would have loved if she remained leader cause she wasnt as soft as firestar but she was going crazy in her last moons of life and she needed to redeem herself in the end によって throwing her self off the cliff with the pack of イヌ behind her she was メリダとおそろしの森 and loved her clan and what better way to leave then to know your clan is 安全, 安全です
Yes and no. She was wise and trusting at the start, but grew stubborn when she thought she was at war with StarClan. She called everyone traitors but bought some sense when the died on the riverbank. She is now hunting with StarClan.
I loved Bluestar and thoroughly admired her but if she didn't die then Firestar never would have become leader of ThunderClan. I think that it was better that she died so that Firestar could save all 4 Clans from the darkness that haunts them all.
I think she should have because no cat can live forever, and se was pretty old. and anyway, would the clan be as it is now if Bluestar had lived. Firestar also needed to reveal his specialness, and Bluestar died nobly.
