Explain this quote:"Laila dropped the spoke because she could not accept what the Mujahideen readily had: that sometimes in war innocent life had to be taken."?

Laila thinks of killing herself and her baby. Rasheed has locked them in a room. She, however, refuses to accept, as the Taliban says, that in war innocent life must be sacrificed. Her war is with Rasheed and she will not kill herself or her baby yet.
