It would be foolish to 'seek revenge' on kakashi. Honestly, without the 'zetsu armor', kakashi would win that fight. Also, if Obito killed kakashi, then he would be a hypocrite if he wanted to have his whole 'world peace' idea.
Also, keeping his identity secret involves NOT letting kakashi know he's alive. If kakashi knew obito survived, he would have figured out who tobi was almost instantly.
I see no qualms with obito not directly confronting kakashi. Besides, we don't know what happens yet.
