It’s worse than murder because

• the state MUST be held to the highest standard;
• the state has the resources to do other than kill;
• execution ends up costing the state more than life imprisonment or better solutions;
• because someone who is ready to murder typically already does not fear punishment of any severity;
• because resources spent on decreasing economic inequality decrease the murder rate far more effectively than capital punishment ever can;
• etc.
