Phewww, thank heavens for Davina. I was reading through this shaking my head "That's not what was said".
Yes, all that was meant was that he was of a similar mindset. The value of ; life is lost on Moriarty. He only sees its value as being another commodity to make deals with, another object to be used as bait, another possession to be thrown away at will. This is how a suicide bomber and more importantly those who control the suicide bombers think.
There's no hint that Moriarty was not at the top of food chain in his organisation. He was the spider alright.
See how misreading something or putting the wrong meaning to something sparks off thinking along the wrong tangent? There's heaps of things like this eg "I prefer to text". But I will leave those for another time.

Mycroft’s popularity doesn’t surprise me at all. He is, after all, incredibly beautiful, clever and well-dressed. And beautiful. Did I mention that?
