Taking something, whether it be goods or service, without paying for it is theft pure and simple. If your moral compass will allow you to do that then no argument on here will persuade you that you are wrong. However, be prepared to accept that a judge may not see things in the same light as you. Also be prepared that the place where you may be arguing your case may be a country where theft is viewed a little more harshly than the in the western world. Remember the law of the land you are in applies with the doors open - so if you fly into Saudi Arabia, then you will be charged with theft in Saudi Arabia.
The old maxim of if you can't do the time don't do the crime is very apt here. Also gaining a criminal record can directly affect your career prospects - many employers take a dim view of their employees engaging in criminal activity. But hey if you are happy to be a thief, please do carry on.
