But that does not make the result of the abort correct.
Not aborting will loop infinitely.

If. D does stop running though, because the H that it calls aborts the
recursive emulation in order to be a decider.

Again a claim without evidence.
If true, the abort criteria are incorrect.
The last one does not need to be aborted, because it returns after N cycles of simulations, when the simulated HHH aborts and returns.
Only infinite simulations need to be aborted.
Is that too difficult to understand?
Your thinking is running in void circles:
Because HHH aborts you think it is an infinite recursion and because you think HHH is doing an infinite recursion you think it needs to be aborted.
But that is incorrect. The correct reasoning is:
Because HHH aborts, it is not an infinite recursion and because there is no infinite recursion no abort is needed.
The simulation of an aborting HHH does not need to be aborted. Only the simulation of a non-aborting HHH needs to be aborted.
This proves that neither an aborting HHH, not a non-aborting HHH is able to correctly simulate itself. (Although they might simulate each other.)

 void Infinite_Loop()
{
   HERE: goto HERE;
}
 void Infinite_Recursion()
{
   Infinite_Recursion();
}
 void DDD()
{
   HHH(DDD);
}
 int main()
{
   HHH(Infinite_Loop);
   HHH(Infinite_Recursion);
   HHH(DDD);
}
 

void Finite_Recursion (int N) {
   if (N != 0) Finite_Recursion (N - 1);
}
This is equivalent to you HHH that simulates N cycles.
No abort needed.
