When HHH correctly emulates N steps of the
above functions none of them can possibly reach
their own "return" instruction and terminate normally.

Nevertheless, assuming HHH is a decider, Infinite_Loop and Infinite_Recursion
specify a non-terminating behaviour, DDD specifies a terminating behaviour

 Irrelevant off-topic distraction.
 

Proving that you don't have a clue that Rice's Theorem
is anchored in the behavior that its finite string input
specifies. The depth of your knowledge is memorizing
quotes from textbooks.
