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: The truth is that the Death Penalty punishes those who have convicted a crime of extreme severity, not any criminal who commits a crime.
 Sent2: The death penalty is simply a legally imposed punishment given to felons who commited crimes for which the death penalty is applicable.

SOLUTION: Similar

PROBLEM: Sent1: If they know they'll die if caught, they'll likely kill more rape victims and children.
 Sent2: >>>If we are sure they raped & killed those innocent children then we should let them die.

SOLUTION: Not similar

PROBLEM: Sent1: So, the only reason I can really see why people support the death penalty is to have simple vengeance against the perpretrator.
 Sent2: It is proved that death penalty for such kind people is the simplest punishment.

SOLUTION:
Not similar
