it's not obvious that trading on material, non-public information that you overheard is unethical. it's basically the same thing as winning the lottery, and i wouldn't not cash in lottery winnings because i have the opportunity to build something of great value to others (that's neither here nor there). it's not even obvious that insider trading should be illegal (http://business.time.com/2013/07/26/why-is-insider-trading-even-illegal/ http://business.time.com/2013/07/26/why-is-insider-trading-e...). (not particularly relevant, but i do think certain types of insider trading should definitely be illegal but the scope is debatable.)
