Roslin's motivation was, first and foremost, to cause another war, right? Like, he WANTED money, but for whatever reason(sadism or simply revenge against a world that made BEING ALIVE illegal for him), he wanted another war, and Blakemore's little idea gave him the best way to do that. It would make him wealthy too, but the war was always what he really wanted.

So...do you think he set up a dead man's switch transmitter with all the info on the Roslin project, plus the 'Evil Plan'(TM) from game one that was to fake Okkar attacks on Human interests? Because the whole reason Hawke gives to killing all those Adam's to the point of being very familiar with them was that would be what would happen if word got out he existed. So I'd have loaded that up onto a few hidden beacons in the DMZ, ready to go off if I stopped telling them not to, at random times too, so taking one out doesn't mean crud, AND you can't plan for them not to transmit in places you can get to in time.

It wouldn't be as clean as defiling a holy icon, maybe only some Okkar would want war from it, but it WOULD still fulfill his wish.
