Sutra:
285. chakravarththi thirumagan pApaththOdE varilum amaiyum enRAn; ivan puNyaththaip pOgattu varavENum enRAn.

Sri PBA Swami's Sarartha Deepikai:
Instead, will this work if the chetana performs good acts?

This is not desired by the Lord.

The examples for that are:
1. When Sri Rama sent Sugreeva to bring Vibeeshana to Him, He said "yadi vA rAvaNa: svayam". That is, Rama asked that even if it is the great sinner Ravana, that he be brought to Him. Since, sins are not the path to reach Him, it is seen that even if one is a sinner it will work (if He desires it).
2. Lord Krishna, by saying "sarva dharmAn parityajya", asks that the chetana give up the good acts, which might be thought of as required for the goal, as well.

Therefore, the Lord who does not tolerate the other paths will not desire the good acts on the part of the chetana either.
