Just an idle thought
Neither Kate nor the shop owner had ever, to our knowledge, done anything against Adler and they're both dead. Mozzie wasn't even known by Adler and probably was only targeted because he figured out the code.
Alex and Neal are the only one who were known by Adler and were actually going after Adler to take him. Also, it was obvious from the anagram he'd left Neal that Adler knew who Neal was and he does know who Alex is. Yet no move has actually been made to kill either Alex or Neal. After this last episode I think the plan was to kill Kate before Neal's eyes. It would not have mattered if Peter was there or not.
So my moment of speculation brings me to the idea that Adler wants to "own" Neal in one way or another but he definitely wants to hurt him in every way he can but we don't know the reason why. Both Neal and Alex tried to swindle him, but Adler swindled Neal in the end.
A conundrum.
