We know from the data that capital punishment is not a deterrent. Hence the out of control drug war. While it would feel good, what we'd end up doing is creating a set of super criminals who make it impossible to figure out that they are stealing the election. Hence the saying that best hackers are 10 steps ahead of the law enforcement agencies (by the time the authorities figure out those hackers methods, the hackers have adapted and modernized 10 more times meaning all the stuff that the authorities are picking up are just bread crumbs from outdated methods from the best hackers - almost all great hackers caught as hackers that get complacent/arrogant and don't follow their own methods). Same thing for the drug mules - they just keep figure out better ways. Capital punishment is what you use when there is no chance to rehabilitate or the crimes are so heinous that society is unwilling to rehabilitate the criminal for reintegration. AKA, someone like Ed Gein. You don't do it to deter, you do it to remove a burden from the system that is unnecessary or even unwanted. Technically, I'd be a capital punishment candidate in an Muslim country because of some of my beliefs. No chance killing me would deter others who hold my same beliefs (such as you). In fact, it may strengthen your resolve because one of your brother died for an evil cause.
