Oh, I definitely don't think her decisions qualify as 'right', but I also don't think that there's any decision that she could make that would. So. 'Sucks to be Boomer' is how this tune goes, I think. It's been playing since the first season.

I also agree that she feels intense envy toward Athena (if she didn't, she would have been... nicer about knocking her out). Athena was aware of the genocide and was part of the cylons until she fell in love... but she's been able to have happiness and love. Meanwhile, Boomer is doing the 'if I didn't have bad luck, I'd have no luck at all' dance.
