After reading this you really don't have an ethics question.
An ethics question would examine whether something was right or wrong,
such as in this case - stealing. I refuse to believe that you don't know stealing is wrong.
It's really a "getting away with it" question. And if you can get away with something does that make it OK to do. It doesn't.
Stealing, from someone who has so much anyway, or is an evil empire, or who
"screwed you" once, or "no one will ever know" is still stealing. You are simply trying to justify your actions by deeds or misdeeds of others. The human mind is a wonderful thing. There is nothing too low that we can't justify.
So yes, you can be a thief and not feel bad.
You want to know if you can be comfortable lowering yourself? Then the masses have spoken: "go for it dude!".
Just let me know when you are away. See, if I can get together with your spouse, and you never find out about it..........
