B.G 9.30 to 33
api cet sudurācāro bhajate māmananyabhāk। sādhureva sa mantavyaḥ samyag vyavasito hi saḥ ॥30॥
Even if one is extremely ill-behaved, if he worships Me with exclusive devotion, he is to be considered saintly, for he is rightly resolved.
kṣipraṁ bhavati dharmātmā śaśvacchāntiṁ nigacchati। kaunteya pratijānīhi na me bhaktaḥ praṇaśyati ॥31॥
He quickly becomes righteous and attains eternal peace; O son of Kunti, understand conclusively that My devotee never perishes.
māṁ hi pārtha vyapāśritya ye'pi syuḥ pāpayonayaḥ। striyo vaiśyāstathā śūdrāste'pi yānti parāṁ gatim ॥32॥
Even those of sinful birth - women, merchants, and labourers, if they take refuge in Me, O Arjuna, they too attain the supreme destination.
kiṁ punarbrāhmaṇāḥ puṇyā bhaktā rājarṣayastathā। anityamasukhaṁ lokamimaṁ prāpya bhajasva mām ॥33॥
What to speak then of virtuous Brahmins and royal sages who are devoted? Having attained this impermanent and joyless world, worship Me.
Gīta Bhāshya 9.30 to 33
The Lord devotees generally does not misbehave. But because of unwinding of karma, temporarily he may misbehave.
na bhavatyeva prāyaḥ tad bhaktaḥ sudurācāraḥ। tathāpi bahupuṇyena yadi kathañcit bhavati tarhi sādhureva sa mantavyaḥ ॥30॥
Generally, a devotee does not become extremely ill-behaved; yet, because of excessive merit, somehow, he does, even then he is to be considered saintly.
