This article focus on the death penalty as a deterrent to terrorism crime in Indonesia.  Earlier proponents agree that the death penalty should be useful as often as possible to prevent future crimes and provide a sense of justice and moral order. However, abolitionist agrees that the death penalty does not address future murders. Execution is brutalization and human sacrifice without consistent or reliable evidence that execution's de jure availability had a deterrent effect on homicides—the death penalty is undeniably cruel, inhuman, and degrading. The death penalty does not deter criminals; imprisonment is more significant as a deterrent against the perpetrator. This is doctrinal research that uses a religious-legal approach and uses indoctrination theory to assess the problems. The result shows there is no significant effect of the death penalty on crimes of terrorism in Indonesia due to indoctrination that killings humans are a way to heaven to meet angles heaven.
