Even if McCree has not dared to break eye contact (or what counts for it when he's looking at two dark empty sockets on a mask) he can see in his periphery where that hand is going. He's of no opinion that it should stop, no flinch or hesitate to indicate he's thinking even remotely twice about this.

There is a dull, warning in the back of his head that this is probably breaking Legion legislation or something, but it's easily ignored. He's never been one for rules. Besides... there's one perfectly good reason to not fear the Reaper in this instance.

"..."

The silence draws, thick and long, and McCree soaks up every tension-filled second like he needs it to breathe. There's a glimmer in his eye that wouldn't ask for anything less than this moment.

Then he breaks it in the blink of an eye and fires right for that nice white spot between those two dark empty sockets.
