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.

I think the death penalty should only be used in extreme cases where the accused is, without a doubt, guilty.
Valid

The definitions of terms I used were a simplistic formulation of those found in texts, with differing points enhanced.
Invalid

Still a hard choice for me, but I am too close to it, therefore I fear I will never have a solid opinion either way.

Invalid
