Not to pick nits or anything, but we don't know exactly how many people were on Cloud Nine when it blew up.
50,000 in fleet before colonization of New Caprica - 39,000 residents of New Caprica City does not equal 11,000 killed by nuke because of the thousands of people still in the fleet.
I'm guessing more like 1,000 killed in nuke + 10,000 left in ships.
So Baltar is only responsible for the deaths of billions + maybe 1000 more, not billions + 11,000. So go easy on the guy.
