But those who carp at My teaching and do not practise it, deluded of all knowledge, and devoid of discrimination, know them to be doomed to destruction.

But those who find fault with it and do not follow my teaching, know them to be deluded in all knowledge, lost and without discernment.

The verse states the opposite case. Those who resent the teaching and refuse to practise it are described as confused about all knowledge, lost and lacking discernment. The language is strong, but the point is not condemnation for its own sake. Krishna is stressing that the teaching is meant to be lived, not merely heard. One who rejects it out of hostility closes the door to the very understanding that could free him. The pair of verses shows how much the inner attitude of the listener matters.
