Real life Dr Evil can't afford to wipe out world population

An unsolicited email (full text available to anyone interested!) led me to this website. It strikes me that with technology having reached the state it has, the main force preventing some maniac wiping out the entire world population is that nobody stupid enough to want to wipe out the entire world population can afford the means to do it. There are certainly, and almost certainly have always been, people who are really pissed off with the world and would like to wipe out humanity - most people at some point in their teens, probably! Fortunately almost all of them are rendered harmless by lack of cash. The author of the website referred to above seemed a good potential Dr Evil, but thought I ought to check so sent him this email: You hold in your hand a vial containing a deadly virus. If you crush the vial the virus will escape and eventually infect and kill (shall we say painlessly for the sake of argument) every single fake. The virus only affects fakes and will leave yourself, your ally and everyone else of similar mindset alive. Perhaps only 3 or 4 people in the world would be left. Would you do it? Those of you who are sufficiently well versed in the classics will recognise that this is almost a straight quotation from "Dr Who and the Genesis of the Daleks". His response was: I see no reason why not use it. If I don't have time to think about it I would probably do it, if I do have time to think about it I'd try to consider as many factors as possible just in case. The only misc. factor that I see as being quite vital is to know that at least some of the people left would be female since we wouldn't have access to any cloning technology with society gone, and without offspring it would be quite unlikely to build a new generation. In the exact situation you described there would be no particular urgency in using this vial so I would imagine some preparation would make sense. Also I see no particular relevance of it being "painless" since pain is nothing more then a biological reaction to certain stimuli. I also don't think it's extremely important that every single one of those like us is left alive as long as the number remaining is enough to start with (that is, if the vial had risk of killing some that think like us it should still be acceptable as long as we knew the number remaining would be enough to proceed with). I'm only answering this because it's a catchy question, I doubt this communication will go much further because of the very little effort you put in your contact attempt. Not quite as rousing a speech as the one Davros made (where he started off along the same lines saying he would use the virus, and ended up ranting about how Daleks would rule supreme etc) but quite mad nonetheless. I just hope this guy doesn't have any cash...
