there will always remain a thin line between white and black hats.
i myself have been a "black" hat and have known and still know "black" hats,but there comes a natural progression...almost an evolution of some kind that usually leads to the "white" hat ethics
its like a child growing into a man.
having power to use and the knowledge to use it doesnt always justify the means.
i would never advise anyone to be involved with black hat hacking,but try to remain true to your ethical code and use your knowledge to find flaws only to help better the communitiy at large.
