Danzou and the Uchiha Clan

So with the latest naruto manga chapter 478 we get a few tasters of Danzous 'real' power. It was evident before that Danzou and other powers in Konoha had perhaps ordered Itachi to kill off the Uchiha Clan to protect Konoha from the Uchiha coup d'etat.

Now though it appears there might be more to it on Danzou's part after we see the Sharingan eyes embedded in his arm. Was the power of the Sharingan Danzou's main goal, and not to protect Konoha?

Also, I don't know about you but I found the previous chapter ended in a way that really mislead you to think Itachi might not be dead, only to be subtly told in the last chapter that it was just an illusion, gahh.

In the next chapter we find out more about the Forbidden Jutsu Izanagi!
