Question to the integrity police: If you had a million dollar winning lottery ticket, and before you knew that they were the winning numbers you verbally told someone you'd give it to them for free because you don't believe in the lottery, would you still give it away for free? Be honest don't go for karma points.
Tell yourself whatever you need to to make yourself feel better. If the facts are as stated, which they appear to be, it's a pretty lousy thing to do.
