AWOL is dangerous because you are alluding to very negative things about Corrie.
Firstly, his relationship to his family. You are alluding that they hide things from each other, despite the frequent and adament statement that they know Corrie very well, and are a very close knit family. That he would withhold information from his mother, brother, etc, it's a dark approach, and yet there are no indiciations, even the slightest, that there is a hint of darkness about this chap. He had some beers with friends, he grabbed a kebab and strutted down the street, had a nap and then did a pee or something, and then he was gone. Along with the family statements and the facts, videos etc we do have to go on, it's just hard to stack that up to a premeditated AWOL IMO.
Secondly that, should he say, have shadier rendevous that might lead to an AWOL with or without help, that then he is perhaps in some ways unprofessional as a military man, yet it seems that he is a man who does his duty, has integrity (toward his career and family) and that has a routine well understood by those close to him (colleagues) and even those who aren't (ie the kebab seller).
In similar fashion perhaps, the MH370 pilot (the plane that disappeared). Attested to be a great, sound guy with no financial problems etc and a loving father by the family, but speculated by others to perhaps have sinister motives, despite it being contrary to character completely, a man who has served as a captain for so many years. Which one do you go with? Furthermore, you may never have proof of the AWOL but you'll always have proof of the family relationship, again, which one do you go with?
I'm not saying it's the wrong thing, I'm just saying I feel the evidence points the other way. The psychological and interpersonal aspects (or testimony, at least) does not add up to an AWOL situation.
You also would definitely not make the rendezvous point somewhere with a CCTV camera pointing where's theres no exit other than on camera - even if you only had half a brain cell. Yet the trail goes cold in that Horseshoe place, where we are left wondering if a car drove him off from that point. From descriptions of inner and outer rings (regarding CCTV) it sounds like the last place you'd want to be pulling off something discrete. It's not impossible to make that CCTV oversight, it's just absolutely shoddy compared to the complexity of the rest of the speculative AWOL scenario (as in everything else we've got after that point, which is nothing, other than a phone ping).
I realize it's probably better to stay impartial, but I like to consider the human element, and I don't see any deception in the family ranks, or immediate colleagues or anywhere, myself. As such, I think AWOL portrays Corrie in a negative light, and I don't support that theory. Or maybe it's that I don't WANT to support that theory, if you know what I mean? If I disappear please try and follow my positive trail, not some dark angle of me, it's probably not true, k thx
