That seems scummy right there. Jumping on the wagon even without believing it to be true and putting him close to something that could come down to a hammer. Easy set up, and not done very well in my opinion.
I don't think any scum would be dumb enough to reveal who they will be killing over night. It's common knowledge that after a doc claim, that person is a highly likely target for a NK. I don't see how Akira stating that makes it any less true and any more likely that he's scum.
His previous posts don't indicate such lack of thought to post something as revealing as he did, and so I'm not convinced.
