Arjuna said But impelled by what does man commit sin, though against his wishes, O Varshneya (Krishna), constrained as it were, by force?

Arjuna said: Then, descendant of Vrishni, what drives a person to commit sin, even against his will, as though compelled by force?

Arjuna asks a deeply human question. If one knows what is right, why does one still do wrong, unwillingly, as if pushed by some force? It is the ancient problem of weakness of will: people often see the good and yet act against it. Arjuna's question shows that he is now engaging with the teaching seriously, not only defending his own position. It leads Krishna into the final section of the chapter, which identifies the inner enemy that overpowers knowledge and drives people into harmful action.
