Sure, if you promise to not sin that takes care of your sins. However we are not (at least at Prabhupada's times we were not) obsessed with diksa, but with spreading the knowledge and mission of Krishna. Besides Uttama adhikari is a devotee who is defined by Prabhupada as: An uttama-adhikari is not interested in blaspheming others, his heart is completely clean, and he has attained the realized state of unalloyed Krsna consciousness.

It is not found often however he had said: When a neophyte devotee is actually initiated and engaged in devotional service by the orders of the spiritual master, he should be accepted immediately as a bona fide Vaisnava, and obeisances should be offered unto him. Out of many such Vaisnavas, one may be found to be very seriously engaged in the service of the Lord and strictly following all the regulative principles, chanting the prescribed number of rounds on japa beads and always thinking of how to expand the Krsna consciousness movement. Such a Vaisnava should be accepted as an uttama-adhikari, a highly advanced devotee, and his association should always be sought.

Actually both Shila Prabhupada and Shrila Bhaktisiddhanta had said that they suffer due to taking too many neophyte disciples.

Neophyte disciples are actually initiated, otherwise why would guru suffer from accepting so many disciples? But they are still neophytes. On the other hand if one accepts a madhyamaadhikari as a sishya, one is not suffering so much because this sishya will propagate the message of Shee Mahaprabhu, and is His associate in samkirtan mission.

Sometimes Srila Prabhupada humbly spoke like this about himself, saying that he accepted too many unqualified disciples and had to suffer as a result. Certainly it was clear that he was disturbed by some of their activities. Yet if one scrutinizes his teaching, it also becomes clear that the karma of the disciple is gradually destroyed in proportion to his or her adherence to the guidelines of sri guru. Thus if the guru is qualified, the onus is on the disciples to follow sincerely. If they do so, the disciples will themselves become free from karma as they attain Krishna consciousness.

Srila Prabhupada states, “An initiated devotee is given the chance for becoming free from the entanglement of karma wheel. Initiated means beginning, not perfection. The spiritual master’s business is to guide him to the perfectional point. But if one does not strictly follow the guidance of a bona fide spiritual master, his initiation does not bear any meaning. The initiation performance is an agreement by the disciples to abide by the order of the spiritual master. Therefore, if the spiritual master is bona fide and the disciple is serious to abide by his order, then the success is sure. But if a disciple follows strictly the devotional way of life, he is no longer a karmi and all his activities, which may appear to be like ordinary work, or it may be activity according to scriptural injunction, are counted as devotional service. And devotional service in all circumstances is free from the actions and reactions of karma.”
