'So we’ve hit this looter a dozen times /and he’s there on the ground,'
Pronoun/Noun: It seems important for the speaker to distance himself from his victim.
He speaks about him in quite a callous way, possibly to avoid facing the reality of what he’s done.
He has also reverted back to his previous nonchalant tone.
Clearly, the speaker feels the need to maintain the veneer of indifference in order to cope with the memory.
