Should one worship Krishna unfavorably?

One should not try to worship Krishna unfavorably; otherwise he must be punished, at least for one life, to be purified. As one should not try to be killed by embracing an enemy, a tiger or a snake, one should not blaspheme the Supreme Personality of Godhead and become His enemy in order to be put into hellish life.
