The terror, terrorists, and terrorism are more common phenomenon and flaming issues in the world, today and Bangladesh is not excluded from that. By taking the example of torture and extra-judicial killing by RAB in Bangladesh, one could understand/examine the ethical and legal position of use of torture and extra-judicial killing that are taking place every day around the world in the name of war against terrorism or to maintain world peace or even to protect citizens. Against this background the study analyses briefly the legal status and in greater detail the ethical status of the torture that have been purportedly committed by the RAB in Bangladesh since 2004.  The first section of this research discusses the background of RAB, the various instances and nature of torture and extra-judicial killings purportedly committed by RAB and then shows how such acts are gross violation of both International and Domestic Law. The second part of this paper looks into the instances of torture by the squad in relation to whether it satisfies the well-established ethical standards and also argues that in most instances torture is unethical.
