When someone says "oNLy gOd caN jUDgE mE" they are attempting to place themselves beyond reproach.
Yes, some judgement is bad. Like most things, it's not a black-and-white issue. But some level of discernment and action based on a person's demeanor, ethics and actions is essential to a functioning society. Imagine the serial killer who thinks they are immune to human judgement. (I wonder how many there have been?) Is this belief harmful or helpful? Is it CORRECT? </rant>
@aspecurian Biblically speaking, the belief is incorrect. The book of proverbs is almost entirely about exercising judgement with wisdom.
Yes, there is the eternal perspective of "do not judge or you will be judged" but that does not release anybody from responsibilty for their actions in this world. It is simply another way of saying "you reap what you sow, so watch yourself!"
@stueytheround The Law of Unintended Consequences has many names.
In my belief system it's called Karma.
