Cedric knew that he was no match for Rholas because of the apostle's ability to use divine powers. Rholas himself was not a threat if Cedric used everything he had, but Aegis was a god. Even if a sliver of his will existed in the apostle, Cedric would not be a match.
There was no use in attempting to kill Rholas before Aegis incarnated in his body because death would trigger a bigger reaction from the apostles. It was a wonder how Morrin managed to kill one of them.
