I only pirate something if I know it is impossible to get any other way or I want something that I can put onto a disc for backup if I bought the game off Steam, eg, Monkey 1 and 2; I still bought them, but got a pirated version just to put on a disc.
I don't really know if this counts as pirating, but sometimes I crack games I have, but only because I can't be stuffed having a disc in the machine the whole time. Again, this is only with games I have actually bought.
As far as my views are concerned, I don't see it as some massive issue, but I still think that people should only do it for backup reasons.
