He's pissed because Nagato was supposed to ressurect him, nothing to do with kabuto.
I think rin sold out/ was a spy, if those ninja from the start were mist-nin that kidnapped her before, maybe she allowed herself to be captured? it was a trap? and when kakashi found this out he went on a rampage. or she sold out for some other reason.
or maybe madara had a hand in in, i mean the zetsu clones new everything that was happened with rin and kakashi, and they told obito to go at the most crucial time, could be just all a set up, obito will redeem himself, I know it. He's at heart not like madara hes more of a itachi.
To be honest naruto manga has died down now, and bleach has just started to kick in, both take the fukin piss.
