You're at the self-checkout at the shop with a parent who's stepped away to grab one more thing. You're scanning the items. One of them — a chocolate bar — doesn't beep, and the screen doesn't add it. You realise you could just put it in the bag and you'd be getting it for free. Nobody's watching. The machine missed it. It wouldn't even feel like stealing, exactly. It's a small thing. A chocolate bar. The shop is huge and won't miss it. Your parent isn't looking, the machine didn't catch it, and you could slide it into the bag in one second. The only person who would ever know what you decided in this moment is you. So the question isn't really about the chocolate. It's about you.
