Given his desire to get both Cassie and Sheba off the Pegasus before taking on Baltar, I think not. he's realized that having Sheba there was perhaps bad enough. After Molacay, he had no choice. But now...I think even Cain realizes that having daughter and lover aboard at the same time is a recipe for fireworks. Plus, having both child and sex partner could become erosive of morale after a time. I think Cain is wise enough to know that to lead effectively, he must, like Caesar or Washington, share in his men's deprivations, not put himself above them.
I think his desire to get them off the Pegasus had more to do with the fact that it was a near suicide mission, rather than it being any kind of sacrificial command decision. Cain struck me much more as a man who would satisfy his ego and desires, rather than do without to impress his men. Else he would have worn less brocade.
