Mirror, mirror, at the door
Not focusing on others’ faults doesn’t mean that we never recognize they have delusions (uncontrolled, unpeaceful minds) or develop the wish to help them overcome these – our mistake is conflating the person with the delusions. As my teacher says:
It is because they distinguish between delusions and persons that Buddhas are able to see the faults of delusions without ever seeing a single fault in any living being. Consequently, their love and compassion for living beings never diminish. ~ Transform Your Life, p 131
