I think Wyatt (who was referred to as a sociopath by Susanna) is merely trying to rationalize his behavior- -to make it seem ok that he spent a large part of his life killing people for money. For some reason, this job really seemed to shake him, and I sensed that he did not like what he needed to do to the couple in the parking garage.
I definitely don't agree with his word choice. Deserve? And now my brain is quickly tangenting to the bigger question- -does anyone really deserve anything? And why am I all of the sudden attaching such a negative connotation to that word?
