Cain was mainly concerned with attacking the Cylons and keeping the Pegasus going. The rest of humanity were either needed to achieve this or obstacles, ones that she had no problem removing. If her chief goal was to keep the human race alive, then the Pegasus would have had its own fleet. While wiping out the Cylons can be seen as a worthy goal and would save what's left of humanity, she was clearly more focused on taking out the Cylons even if the human race went extinct in the process.
Her goal wasn't to wipe out the Cylons. It was to fight a smart guerrilla war with the goal of taking back their home, Caprica. The whole revenge thing was a rah-rah speech to get the troops going after they learned of the genocide. In the next scene, she states her real goal.
