Oh yeah, Carolina personality fractured actually, he'll be pleasant and nice and in combat he'll default to his good old jack-ass personality. Not to mention the nightmares and possible trauma if one of the team actually does die. He kept beating the odds, it's what he's trained to do. He kept beating F.L.I.S.S. ways to defeat him, so they kept it going, wanting to see what it took to break his system and instead broke him.
