 Reviewers observed that religion plays an influential role in Marty 's moral decisions . After Marty takes a forbidden bite from his sister Dara Lynn 's chocolate Easter rabbit and refuses to own up , his mother is disappointed . She tells him : " Dara Lynn don 't know who ate the ear off her candy rabbit and I don 't know who did it , but Jesus knows . And right this minute Jesus is looking down with the saddest eyes on the person who ate that chocolate . " Marty 's very religious mother teaches him that people should not sin or they will be " separated forever from God 's love . "
