I dont see a reason, for Mortals to be compared to Gods. Hinduism follows the basic principles of nature as we reap what is sowed. Even the gods are no exception and get punished of their wrong deeds.(Lord Krishna died a horibble death and his city got drowned owing to his fights and killings). What people quote are just what is superficial . If you have any real interest than it is necessary to understand the idealogy.Gods are gods because they have qualities of Superhuman .Lord Krishna seeks to remove Caste bias and to follow the true religon of Karma.As can be seen from his life and narrative Gita that instructs Arjun on battlefield about his duties to his brothers and helps him differentiate the right from the Wrong. First we have to have these qualities, then to impersonate them. As such every god stand for his qualities . Krishna stands for compasion. Shiva for his temper and Simpleness. Rama for his devotedness to Janaki and righteousness. If you see thing wrong here, others are worse if not equal.
