Not according to the laws of most of the countries I am familiar with (assuming you mean copyright infringement). And, as I've pointed out, copyright infringement is not a criminal offense in certain jurisdictions.
There are in fact grey areas, both within the law and ethically. If the only copy of a film is decaying, and you cannot locate the copyright owner, can you make a copy to preserve it? Both legally and ethically, this is a grey area.
Not to mention that the definition of fair use in US law requires context to be taken into account and needs to be determined on a case-by-case basis, as per the legislation! How is that *not* a grey area?
Finally, certain types of copyright infringement are explicitly legal in some circumstances, even if the publisher does not give permission. If I take Eden's PDF and make a Braille version, is that infringement? Is that ethical? The answer depends on what country I'm standing in.
