It’s been quite a long while since I’ve seen the film. So, what if the younger Tom Riddle was successful of coming back to life, wouldn’t he become a dangerous threat to the real Voldemort?

Surely he would be as selfish, evil, scheming, and ambitious. He would attempt to eliminate his frail counterpart in Goblet of Fire, a seemingly loose end.

And why didn’t the other Horcruxes have the same Tom Riddle manifestation?
