Glory. What little is left to accomplish is so trivial as to be pointless.
Frieza has a solution to this however, but the idea of pursuing it was...bothersome.
Who's the only person left who can truly challenge him? Who's the only person who could oppose such overwhelming power?
Karn. His true rival and only friend in this Universe.

It's not hard to imagine that Babidi simply asked him "Why wait?".
