If dead doesn't matter then why are there 7 dead? And only 3 survivors? Why not just maim?
He is doing "torso" shots...some will survive, most won't. He isn't aiming to maim...he is aiming to HIT. He wants the REACTION from the police and media...that is the part of the game that makes the "ritual" part of planning so much fun for him...the by product of a "hit" body is merely the "calling card"...the thing he is getting his "ya - yas" from is the RITUAL of planning...and the end result he is shooting for in this game is the "cat and mouse" game.
He is a serial sniper...it is a GAME...not a MISSION.
