maybe so, but i'm thinking that when Frisk saved Asriel, Asriel may have hit some sort of... "Checkpoint" so to speak. Provided he kept at least one soul, he may be able to use it to prevent himself from regressing into Flowey, but this is my own speculation.

Remember that he said in the true pacifist ending that having a soul inside of him whilst he was himself allowed him to feel compassion again, and the thousands of monster souls within him granted him knowledge of how much those monsters truly cared about Frisk.

As Flowey, he was a soulless being brought back to life with determination, the first golden flower that I speculate to have grown due to his essence carrying some sort of "memory" of the golden flowers in the village and by extension Asriel's own memories. those flowers didn't contain his soul however, so when he came back to life, he was more or less a husk.

Flowey became Asriel upon absorbing 6 souls and every monster soul in the underground, still unfeeling (or perhaps ignorant) and attacks Frisk, despite the love held towards Frisk by the countless monsters he absorbed. It's not until Frisk reminds him of who he is that he feels those souls and comes to the conclusion as to why he keeps Frisk around, Frisk eventually manages to calm the angel of death down and bring him back to his "saner" self.

with the Human souls revolting against Flowey, my speculation dictates that the souls have no real ability to harm anything on their own, they only really transfer power towards organisms and can only harm someone provided they have a body or they stockpile enough energy and release it with a group of other souls towards a single organism to overload it and severely weaken it. We saw this with Flowey, where the souls revolted against him and began spinning around him, likely transfering all the energy they had into him, forcing Flowey to vent the excess power and losing the photoshop form as a result of this, causing him to regress into a weaker version of the normal Flowey (unsure about that). Then again, that's my speculation.

Finally, with what you said about Flowey regaining his monster form, I actually somewhat agree with that. As the god of hyperdeath (what the @$#%! is Hyperdeath?) and the angel of death (why not the angel of Hyperdeath exactly?), he more or less remained the same as Flowey except in physical form. I think that when Frisk saved Asriel, he completed that transformation and brought Asriel back from the abyss (not 100% on whether or not this was temporary or permanant), maybe allowing the real Asriel to fill one (or more) of the human souls with his own mind. then again, heavy speculation.
