If they were able to experiment on her and manipulate her for intel and thats why he killed her then yea he would have a reason to kill himself rather then leave himself for capture to be put through the same thing as Rin. Its alright to be wrong, that isnt the reason. Not a big deal. There is a different reason they wanted her body, whether she was a spy or something special about it, but your reason is not it.
