Maybe I've just gotten a bit cynical from being around the valley so long, but expecting VCs to have a moral conscience that would stop them from doing wrong is probably a bit deluded based on what we have seen in the past. I actually felt like Nguyen sounded like most VCs I've heard about with his talking down to others, trying to intimidate them, etc. When I think of Silicon Valley VCs I'm a lot more likely to think of stuff like http://betabeat.com/2011/11/charlie-odonnell-women-in-tech-d... than of someone passing on an investment for moral reasons.
