But what was it Arjuna desired to see? He desired to see those of the opposing army gathered there desirous of doing what was agreeable to Duryodhana, this is the construction.

Madhvacarya has no commentary so we present Baladeva Vidyabhusana's.

So Arjuna is saying to Lord Krishna let me scrutinise those friends of mine who have chosen to join the ranks of the Kauravas for satisfying the evil minded Duryodhana instead of opposing him for eradicating his evil mindedness which denotes he does not even know how to protect his own life. This request is reasonable in order to view my opponents.

It could be asked of Arjuna, doesn't he already know the worth of his opponents on the battlefield? Certainly Arjuna is fully cognizant of the worthiness of Bhishma and Drona as case in point as well as so many others. But in this verse this objection would be clarified by Arjuna's reply that he wishes to see all those who are favouring the evil minded Duryodhana, the son of Dhritarastra.
