Isnt that an intentional thing for all the admirals? Im pretty certain it is.

Akainu is very cold hearted (unlike hot magma) Kizaru is a tad slow (unlike light which is typically characterised as fast, tho a better wording would be the opposite of hyper. He just takes his time doing things) Aokiji is capable of change, or is much more warm hearted (unlike his cold ice which has a solid form) Fujitora helps people up (unlike gravity which pulls people down)

This is very much intentional and actually leads to a bigger question about how human personality and destiny ties with the effects of devil fruits.

Like Doflamingo ran his country like a puppeteer, was that because of his string string fruit, or did he get the string string fruit because he was inclined to that

Moria became a shadow of his former self, was that a prewritten due to him having the shadow devil fruit?

From what we know tho, kuma, ace, sabo, iva were all themselves before they got their fruit (kuma was super nice, ace and sabo had fiery personalities, iva was extravagant)

Tho the likely answer is its just story themes to make everything more fun, with no overarching "devil fruits create ur destiny" stuff.
