At the end of Razor Adama, after studying the totality of Cain's tactics declares he cannot find fault with any of the tacitics Cain used. Starbuck declares the fleet is less safe without her. Pretty much everyone on the Pegasus agree with this statement. This last point takes care of all the various gaps that the on-screen time doesn't provide us.
please stop saying this over and over again. it isn't proof. why didn't you try the 'cain wanted to protect humans' line again too?
one mission is not a guerilla war
LOL...that mission took setup...that's how they ran into Galactica. And that mission is but a slice of what we were shown of her adventures. Battestar had twenty something episodes before we saw Cain. What we didn't see we can only rely on what Adama and the Pegasus' own crew say.
