TASK DEFINITION: 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.
PROBLEM: If that is what you believe, I am compelled to disagree, because people are not by nature benevolent.

SOLUTION: Invalid

PROBLEM: Apparently, the death penalty increases the number of innocents killed.

SOLUTION: Valid

PROBLEM: IMHO, if we have the confidence in our system to throw someone in a cage for the rest of their natural life we should have the same confidence to put someone to death.

SOLUTION:
Valid
