Carol Mason's Killing for Life examines the apocalyptic worldview of the anti-abortion movement, tracing how religious extremism and paramilitary culture merged in the violent wing of the pro-life cause. Mason, a scholar of American studies, analyzes the rhetoric, theology, and cultural context of activists who believed they were justified in killing to stop abortion. She reads anti-abortion literature and propaganda for its apocalyptic themes, showing how activists saw themselves as warriors in a cosmic battle against evil. The book traces connections between anti-abortion extremism and other right-wing movements, including white nationalism and militia culture. Mason is careful to distinguish violent extremists from mainstream pro-life advocacy while showing how mainstream rhetoric could enable radicalization. Killing for Life situates its subject within broader American religious and political history, examining how millennial thinking about end times and holy warfare shaped domestic terrorism. The book is scholarly but accessible, drawing on extensive primary research. Essential reading for anyone seeking to understand religiously motivated violence, the history of the abortion debate, or the cultural conditions that produce terrorism.
