" It's just the right thing to do. It's very simple"... that just about says it all. If money falls off a truck and nobody is looking do you keep it or return it to its owner. If you can shoot a person in the head and grab their money with confidence you will not be found out do you do it?
There is a lot of grey between good and evil, but you know your in the down slope to the latter. How does it feel to know that when push came to shove in the morality play your not only a dirt bag but you glotted about it. Congratulations on your windfall, but I think I need a shower.
