Question: In the Bhagavad Gita, Shri Krishna tells Arjuna, "They are already dead." Can You please discuss this?
While teaching Arjuna, Shri Krishna taught by philosophy and also by psychology. So it is in this psychological teaching technique that He said, "They are already dead." He advised Arjuna always to act for a larger cause. Though the characters on the other side of the war were themselves noble people, they had sided with the wrong side.
Arjuna thought He had free will, but Shri Krishna suggests this is not free will, just destiny.
This was a psychological technique to brainwash him to make him to fight on that day. If it was left to the free will of the soldier, he would not do it. Just like the parents employ techniques to teach children, and in the same way Guru will do this also.
