TASK DEFINITION: We would like you to classify each of the following sets of argument pairs (discussing Death Penalty)  into either SIMILAR or NOT SIMILAR. A pair of arguments is considered SIMILAR if the arguments are about the same FACET (making the same argument), and is considered NOT SIMILAR if they do not have the same FACET. A FACET is a low level issue that often reoccurs in many arguments in support of the author's stance or in attacking the other author's position.
PROBLEM: Sent1: So how about we stop a penalty that has executed innocents?
 Sent2: By the same token, if we keep administering the death penalty while the system is broken, we will have a much greater risk of putting someone innocent to death.

SOLUTION: Similar

PROBLEM: Sent1: Last time I checked, killing doesn't bring persons back to life, so the only reason for the death penalty seems to be revenge.
 Sent2: With all that it has been a very trying time for me and I have had to struggle with how I really felt about the death penalty.

SOLUTION: Not similar

PROBLEM: Sent1: We could get the person who may kill in the future.
 Sent2: If someone keeps killing and killing and killing, we need to stop him from taking lives.

SOLUTION:
Not similar
