No. Harogomo flat oUT said kaguya abused her power. And put ppl in I.T.
It's accompanied by a picture of 5 ppl hooked to the roots of the tree. Flat out meaning she planned to create another fruit. It's why ppl called her a demon. Even further proof of this is the 100,000 white zetsu. They were originally ppl according to Harogomo's knowledge. Where'd they come from if not the by product of creating another chakra fruit?
How I view this situations
-Peoples getting connected to the Shinju is to gather back all their chakra into one for Kaguya absorbed it back, Kaguya cant absorbed humans chakra on the get go, she must prepared a medium for it that is Shinju itself.
Although if she able to absorb Humans chakra on the get go, it take much time.
But it can be two motives, Im never denied that IT method is to create Chakra fruit but there also can be another goal for Kaguya
IT and Shinju motives:-
1) Producing new chakra fruit
2) Gathering back all humans chakra in one place and absorb it.
Those two motives/goals/objectivs which one you want to use can be Kaguya original plan.
-Yes white zetsu is a normal peoples in the beggining, but they are just a by product of Shinju after all their chakra is absorb and then they will get a chakra from shinju under a command of Kaguya to be alive, in NV without chakra you are dead.
-Becoming a Zetsu is not the rule or requirment for producing a Chakra fruit, to produce a chakra fruit either you wait for 1000 years or gather all chakra back for Shinju.
