Would you buy a rare game if you knew it would hurt the owner?

[Final Boss]

If the game was incredibly rare and old and I had hunted for it for years, I'd buy it in a heartbeat. If I wouldn't, someone else would. And that someone else might just sell the game for ten times the price. But I'd promise to buy the kid any new game he wants (within reasonable limits - I'm not gonna get some child I don't even know a limited edition Metal Gear or anything like that). The kid would be too young to value the game for the reasons I would. As far as I know, he'd be pining after it because it was a fun game for him, not a treasure of immense sentimental value. I'm pretty sure I could fix that with a game from the current generation.

Everyone would be happy.

I would first buy the item and hand them the money and say thanks. But once the item was in my hand I would tell them while walking away "oh by the way you're an asshole, your kid deserves better than you". It would be pretty funny.
