Given that Kakashi managed to surprise him later proves that Itachi was right to do so. It also proved an excellent deterrent so they could easily escape.

Unless Evil Itachi was hellbent on becoming blind within a few months like Sasuke, he would still be very conservative with his MS powers. No, I was talking about the possible event that they get cornered down by the village.

At his unhealthy state, he was able to use Tsukuyomi, create a very wide amaterasu without a pause, and use his Susanoo for a while plus other normal jutsu. So, in a situation that they get cornered, Itachi can just use Amaterasu on very important and close by buildings, which will prompt the jonins to do the more important thing, save their people. Kisame would do more of the spam work. Keeping the jonins busy and harmimg the villagers.

And anyways, Itachi already had his backup eye, that is Sasuke. And he kept using medicine for his blindness, it was only a few minutes of pain and a few years of blindness for the succes of the mission of retrieving the most powerful tailed beast from the most powerful hidden village, and to wait till his brother's eyes get strong enough for him, an EMS is worth the wait for evil Itachi.
