Self-realized person does not do any harm to anyone because he knows everyone in relationship with the Supreme. His central point is Krsna. Neither he'll misuse anything. He makes everything proper use. "This nice foodstuff, it is given by Krsna, let it be offered to Krsna." That is not misuse; that is the proper use. "Here is nice rose flower, it is manufactured by Krsna's energy, let it be offered to Krsna." This is self-realization.
