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.

Sent1: If they don't want to kill an innocent person, stick to life in prison.
 Sent2: But it costs more, kills more innocents, and has no more advantages to life in prison.

Sent1: I think that criminals view the death penalty as worse than life imprisonment and worse than temporary solitary confinement within life imprisonment - at least given the conditions in American prisons.
 Sent2: I guess the question begs to be asked to my friends on the left is If life in prisonment is so much worse then the death penalty why do you think most prisoners on death row would choose that option?

Sent1: If somebody is completely innocent and they are executed for a crime they didn't commit (which, with forensics these days, probably will never happen again), that is a problem.
 Sent2: Obviously, if someone were found innocent before execution, they would not be executed.
