how does the prosecuting attorney connect the next case to Meursaults?

The prosecuting attorneyconcludes by comparing Meursault's case to the parricide trial to follow, resolving that Meursault's lack of humanity is much worse than, and a precursor to, the parricide. Meursault has no place in human society since he upholds none of its rules, he states before calling for the death penalty and calling Meursault a monster.
