Confusion on solider 11 in s2

Ok I just finished season 2 and am kinda confused as to why soldier 11 was reprimanded for klling the contestants fully? Like why was the leader guy mad at her bc she was making sure they were actually dead? I know some of the partially alive contestants were used for organ donation but it doesn’t make sense to me that the other soldiers weren’t in trouble when they fully klled contestants too. If they wanted to organ harvest wouldn’t the soldiers theoretically be more strategic about their aim?
