Musar על ברכות 37:27

But delay of repentance is only found among the ignorant, who are sleeping - lounging. They do not turn to their hearts, and they have neither the knowledge nor the understanding to know that they should hurry, to escape for their lives. Some of them are led astray from God, Blessed be He, and they do not believe in punishment for sin. And our rabbis, may their memory be blessed, said (Berakhot 19a), "If you saw a scholar transgress a prohibition at night, do not think badly of him the [next] day; for in truth, he has [already] repented."
