Oh it definitely is not the most likely outcome, unfortunately. I think it's somewhat justified considering his particular family history of being fucked over really hard by divine mandates, he's in a position where he's a little more open-minded than usual about breaking with orthodoxy.
To address your original post, Khenbish acts a little differently in the drinking game if you don't complete his route, which is where a lot of the memes come from (since he didn't have a lot of scenes aside from that one, his intro and some R&D/exploration interactions). There's a funny story about this: I had originally written the scene with the dialogue you now get after his route is finished, where he's more open about his experiences (we didn't have all the kinks of the character straightened out yet); but Minoanon did a couple rewrites to make him more reserved and critical of the other guests (which was a good call and is the version everyone read before this update). For the latest build I dug up that old version and put it back in if the right conditions are met.
