In the United States, the method of execution by injection is the most commonly used, accounting for 88% of all executions. This method is preferred because it is seen as less expensive and less painful compared to other forms of execution. As a result, many states have adopted this approach as their primary means of carrying out the death penalty. Despite its widespread use, execution by injection is not without controversy. Between 1890 and 2010, approximately 7% of executions using this method were either incomplete or considered "poorly" executed. This failure rate is notably higher than that of other execution methods, raising concerns about the reliability and effectiveness of the process. The failures in injection executions can lead to prolonged suffering for the condemned, which contradicts the intention of making the process less cruel. These incidents have sparked debates about the ethical implications and the practical challenges of carrying out the death penalty in a humane manner. The higher failure rate associated with injection has prompted some legal experts and human rights organizations to call for a reevaluation of the method. They argue that the potential for error and the risk of causing unnecessary pain undermine the legitimacy of the death penalty itself, regardless of the method used.
