The current spate of religious terrorism in Nigeria is concealed by the perpetrators as a desire to “fight for God”. It is often argued by the insurgents that they are “fighting for God”. The present level of terrorism in Nigeria, occasioned by the Boko Haram insurgency, is commonly adjudged to be the most devastating in her religious and political history. The act of terrorism has affected economic, political and social development in Nigeria, amidst destruction of lives and property. The objectives of this study include an examination of some common causes of religious terrorism and the attendant panaceas. The study also examined the reinforcement of the perpetrators due to the conviction that they are “fighting for God”. The study applied the historical research design method. The theories of B.F. Skinner and Abraham Maslow which address the principle of reinforcement and motivation respectively underpin the study. Findings from the study revealed that most of the terrorists are reinforced by the conviction that their act would be rewarded through easy opportunity to get to paradise since their actions were perpetrated in favour of God. The study also revealed the common causes of religious terrorism and some immediate panaceas. The recommendations include the education of the religious adherents by the church, mosque, family and other forms of mass enlightenment by the government and non-governmental organizations.
