As we all know Ghatotakcha was one of the eldest Pandava and great destroyer of kaurava forces. He was one of the great Pandava follower and could have been great king after Yudhishthira himself, still why he was not saved from Karna Indra dart.
Indra’s dart could have been destroyed by Krishna Sudarshana disc or Indra’s Vajra or Pasupata or Roudrastra or Brahmshira which all Arjuna had.
Ghatotakcha had to die because he wasn’t a righteous person himself. Krishna had said that if Karna didn’t kill him, then he would have done it himself. As for countering Vasavi Shakti, one could justify the need to send a cannon fodder given what I just said, but it certainly does not justify Krishna’s fear, multiple statments claiming it would have destroyed Arjuna along with his steads, the use of illusions to ensure Karna wouldn’t fire Shakti on Arjuna before the 14th day, etc. None of these plot segments were necessary if it could have been countered.
The Vajras have been used a number of times in the Mahabharata and frankly their performance is frankly underwhelming. I recall Karna grabbed one (made by Shiva) out of the air and threw it back at Ghatodkacha. Ashwatthama also used one on Ghatodkacha and it didn’t work. I don’t recall Arjuna using Indra’s Vajra on the Nivatkavachas to be very effective either. He had to use Pasupata to kill them. The Sudershan Chakra is a weapon Krishna himself wasn’t sure could destroy Karna’s armor or stop Shakti in his self-admissions.
However, Pasupata is the weirdest case. Shiva told Arjuna that he is the only one to recieve it but then we see Karna moving around with one, Drona having one and being easily countered, Atikaya (Ravana’s son) having one, etc. If it could counter everything, then there would also be no need for Krishna to get in the way for Vaishnava astra, or Arjuna to retreat from Bhargavaastra which he himself claimed it had no counters. There’s also the case of Parshurama recieving a weapon superior to Pasupata by Shiva, so it’s fair to assume it wasn’t an all powerful weapon. I think it was Debroy who suggested it was the same as Roudra astra. Few people have argued Krishna worried that Arjuna would not use such a dangerous weapon it battle, but I disagree. He retrieved Pasupata before the Jayadratha vadh because he did not want to keep any options off the table. I’m generally of the opinion that statements about the destruction these astras are mostly hyberpole, they’re probably just like the Brahmastra (low and high order). Hyped for being nuclear weapons, but in effect only produces a rain of arrows.
