@Squinty

Yeah, I've always wondered why Itachi didn't implant Tsukuyomi into Sasuke, instead of Amaterasu. Certainly with Obito's spamming of Kamui, a non-physical attack like Tsukuyomi would have been better. Can one conclude that Itachi thought Obito has a greater likelihood to be killed with Amaterasu rather?

Also, we have to take into consideration that Itachi possibly thought that Obito would recover from any mental damage sustained by Tsukuyomi and not be permanently incapacitated. Interesting thought @Squinty, good job.
