Doubt that Spencer Stone wanted any of this to happen.
Box cutters can be a formidable weapon - Spencer nearly had his thumb severed.
Teacher was murdered by a 14 yo with a box cutter:
Box cutters were used in the 9/11 airplane hijackings - don't think that needs a cite.
Even with box cutters, the 9/11 hijackings were not all successful - ones that wanted to re-take control did (or at least thwarted the attempt)..who knows what happened on the other flights.
From my experience, a loss of a thumb does not lower combat effectiveness ~ it just pisses the guy off. Hey, my thumb is at 80% full use today after it was cut off ! So, talking from my experiences.
A kill with a box cutter is a fluke IMO.
I have cut myself many times with box cutters by accident (cut away from you you say? LOL)
Spencer is a typical airman. Pity he serves under Obummer - he does not deserve his service.
