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: I see what you mean, but i'm still against killing people .
 Sent2: I highly doubt the backing of why you personally would want the death penalty invoked is because you're worried at home that a mass murderer is going to escape and kill you or someone you love... seriously?

SOLUTION: Not similar

PROBLEM: Sent1: How can you justify teaching a generation of children that to stop killers from killing because killing is wrong, we should kill them?
 Sent2: So we kill killers, but in the end, end up with more murders.

SOLUTION: Not similar

PROBLEM: Sent1: With trials and appeals, one execution can end up costing more than a life sentence by the time the execution is actually carried out.
 Sent2: Life imprisonment without parole is more effective than execution, and it is cheaper.

SOLUTION:
Not similar
