Obito himself said that ONLY keeping Kamui's secrets from Itachi has kept him alive, so he knows that Itachi can kill him otherwise. Also, if Konan can figure Kamui out you know damn sure Itachi can.. Itachi just had his own goal and that was to protect Sasuke, then die by Sasuke's hand so killing the Akatsuki and risking death in the process is not something he wanted to do, because even if he did kill them he would drop dead afterwards.
