I don't see it as ironic at all. One way anthropologists studying a society can gauge what that society values is to look at the punishments applied for various transgressions. There are severe consequences for transgressions against things that a society values highly. Thus if a society values each human life as the most precious component of their society, then it is not unreasonable if that society places the most severe penalty on anyone who ends such a life. For that "most severe penalty" to be the ending of the life of the perpetrator, if such judgement is determined with grave concern for all parties involved including the perpetrator, is not ironic. It signals to the members of that society that their very life is the most precious aspect of the society of which they are a member.

And yet we know that people get wrongfully convicted and executed somewhat regularly. If you truly value life highly, you must prefer life in prison over the death penalty. The risk of wrongful execution is unacceptable.
