According to Ohba, Light sees Misa Amane, whom he uses as an accomplice, as a "bad person" who killed people, so he acts emotionally cold towards her and manipulates her, although he pretends to love her, and even says he will marry her. He is only stopped from killing her by the shinigami Rem, who threatens to kill him if she dies early or if he tries to kill her, despite her knowledge that doing so will cause her own death.[1]
