On the Way to Krsna
Bhagavad-gītā  we find that Śrī Kṛṣṇa Himself gives the following verdict:
api cet sudurācāro   
 
  bhajate mām ananya-bhāk   
 
  sādhur eva sa mantavyaḥ   
 
  samyag vyavasito hi saḥ
“Even if one commits the most abominable actions, if he is engaged in devotional service, he is to be considered saintly because he is properly situated.” (Bg. 9.30)
On the mundane platform, what is morality for one person is immorality for another, and what is immorality for one person is morality for another. According to the Hindu conception, the drinking of wine is immoral, whereas in the Western world, wine drinking is not considered immoral but is a common thing. So morality is dependent on time, place, circumstance, social position, etc. There is, however, a sense of morality and immorality in all societies. In this verse Kṛṣṇa points out that even if one is engaged in immoral acts but at the same time is fully in Kṛṣṇa consciousness, he is to be considered a  sādhu  or a saint. In other words, although a person may have some immoral habits due to his past association, if he is engaged fully in Kṛṣṇa consciousness, these habits are not to be considered important. Whatever the case, if one becomes Kṛṣṇa conscious, he will gradually be purified and will become a  sādhu . As one progresses in executing Kṛṣṇa consciousness, his bad habits diminish, and he attains to saintly perfection.
