In his last moments before Sasuke absorbed him, he called himself immortal, destined to basically become a god. If that's not arrogance, I don't know what is.

At any case, there's only so much Kabuto could've done, especially after becoming exposed thanks to Kakashi. And there were so many Sound shinobi in the invasion that your statement is pretty much hollow, unless you're talking about the mission to kill Sasuke, of which the only people that seemed to know about other than Orochimaru and Kabuto were the Sound Genin.

Anyway, Dosu managed to figure out the true nature of that plan on his own, which led to his death, as he wanted to kill Sasuke, and that goal would've been eased if he killed Gaara, and that killed him. At any case, if Dosu somehow managed to find out a little more than Orochimaru let on, especially after finding out that the Reanimation Jutsu is to be used in the invasion, I think it's safe to say that he'd probably do some considerable harm to the Sannin's plans, if not ruin them completely.
