Theft is theft......just because some countries do not have laws against downloads or copyright or some do not enforce the existing laws they do have it does not make it morally acceptable to file share copyright material.
If you found a wallet that someone has dropped it does not give you the right to open it and spend the money....it is still theft and just as bad as pickpocketing or mugging the owner....even if his wallet is full of stolen money or cash he has gained immorally.
