After reading the death of Abhimanyu by BORI and KMG, I asked myself since then, why is his death considered so unjust?
Was he attacked in a group? Yes, but the attack only broke his bow, his horses, his chariot, his sword and the wheel of his chariot. Sure, they threw arrows at him, but Abhimanyu had armor so strong that it was hard to pierce, that's why Drona said it was impenetrable.
In fact, those warriors allowed him to kill a brother of Shakuni, some rathas and soldiers. He then killed the horses of Dussasana's son, and they met in a mace fight where Abhimanyu died in a fair fight.
The truth is that I found Alambusha's death, he died too brutally, much worse than Abhimanyu. Because unlike Abhimanyu, he was pierced on all sides and received such a strong blow from Ghatotkacha that all his bones broke.
Also, as far as I know, Karna broke his arc front, because BORI and KMG never mention that he attacked Abhimanyu from behind, neither Krishna nor Arjuna considered him cut by Adharma.
So, my question is, why is Abhimanyu's death is considered unfair if Alambusha died more brutally, and Shalya died in a similar way?
