If it's so widespread that you cannot do business without engaging in it, than I can understand the helplessness involved and forgive those who have felt forced to engaged in it. Especially if they stopped when they had the chance to do something about it.

If everyone is stealing the food off the lunch cart, and you are going to starve because it gets all stolen and you cant even buy any, it changes your moral obligations. Now, if you are the first to steal, then you deserve the worst punishment applicable, and may god have mercy on your soul.

Apply a little common sense before you get all outraged. It's annoying.
