Given the task definition and input, reply with output. We would like you to assess the QUALITY of each of the following argument (discussing Death Penalty) and determine if the argument is Valid or Invalid. A valid argument is clearly interpretable and either expresses an argument, or a premise or a conclusion that can be used in an argument for the topic of death penalty. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of death penalty.

What you are actually criticizing is the success of a free appeals system and saying that it would have been better to kill an innocent man because that would have been cheaper and made a better point.
