till now it have only been somewhat strong characters that are being able to use CH, the weakest being Hancock, and Naguri(noncannon).

But Aokiji had meet Luffy before and Luffy was( and still is) many levels below him, so there is no reason he would be afraid of his strength. Also Characters not having CH dosen't mean they are weak.
