The debate over capital punishment has gained attention of academicians, researchers and policy makers equally. Support or opposition of capital punishment both are backed by the notion of value of human life. It is a quantitative cross-sectional study in its nature and envisaged to explore the perception about effectiveness of capital punishment. A sample of 600 registered lawyers was selected from five district bar associations of Punjab province through random sampling technique. Data were collected through a selfadministered questionnaire and analyzed by applying suitable statistical tests. The objectives of this were to assess the level of awareness about occurrence and reasons of crimes, reasons to support and oppose capital punishment, opinion about crimes on which capital punishment can be awarded and perception about effectiveness of capital punishment as deterrence. Both descriptive and inferential analyses were carried out and results of this research showed that most of the respondents were aware of the occurrence and reasons of crimes. A vast majority of lawyers were in favor of capital punishment due to its significant role in curbing terrorism and violent crimes, particularly in socio-cultural context of Pakistan. They supported capital punishment as effective mean of deterrence against criminal intent and homicide. Miscarriage of justice and sect based victimization were the reasons to oppose the capital punishment. Risk of innocent execution and flaws in police investigation system were also reasons to oppose the capital punishment. This research revealed that respondents having more awareness regarding causes of the crimes perceived capital punishment more effective. However, there was no relationship between the awareness of capital punishment and perceived effectiveness of capital punishment. There was an inverse relationship between reasons to oppose capital punishment and perceived effectiveness of capital punishment. Multivariate analysis revealed a strong association of awareness about punishment, crimes against person, crimes against state and reasons to support capital punishment with effectiveness of capital punishment.
