I understand, but it makes your nick seem in contradiction to what it's supposed to mean.

But anyway, about the main topic, right and wrong are not always so clear-cut. It has a lot to do with your own environment (neighbourhood/friends/family/etc).  Even if the law says one thing, if nobody you know obeys that law, chances are that you won't obey it either. Take speeding as one example. Or j-walking.  Montreal (my city) probably is the j-walking capital. Sometimes you can't even drive downtown because there is pedestrians just about everywhere crossing the street anywhere no matter what color the light, or if it's even a corner.  Tell a pedestrian in Montreal that's it's illegal, and they'll look at you like you just escaped form a mental institution. They know it's illegal, but nobody cares.
The use of warez or MP3's can be similar. Whenever I mention to people I know that downloading mp3's is illegal, I get asked what planet I live on. Everybody does it.
So, anyway. I'm not saying that it's right. I'm just saying that approaching somebody who downloads MP3's or warez with the "you are a criminal" attitude will solve nothing, and will probably make the other person react in the opposite way as they should.
By the way, no offence intended, but trying to make sure that what I write has no spelling mistakes is also part of what I consider "honour".
