Soul reaper wrote: Shin's Mangekyo almost seems artificial to me, much like Shin himself. It's presence in his eyes, and the little monster thing, in addition to its design and its use of Kamui all makes it seem like it was made instead of grown. Agreed. It all feels extremely Orochimaru to me.

As to Kamui: remember that both Sasuke and Itachi had unlocked Amaterasu. It's not that weird to think someone else got Kamui too.
