Ethics and Wealth

If you had the opportunity to steal $1,000,000 in cash from a wealthy person, and you knew you could get away with it (I know this is difficult to imagine, but just assume for a moment that you knew beyond a shadow of a doubt that no one would ever discover that you were the one who took the money, not even the IRS), would you take it? Let's also assume that the wealthy person would not be financially devastated as a result of losing the money you took. She would be upset and unable to do things she wanted to do with the money, but she would still be pretty wealthy after losing the money. Would you take the money? Why or why not?
