In the Harry Potter series, whether it is the battle more than a decade ago, or the final battle more than a decade later, the Great Demon Lord Voldemort has never been able to defeat the little Harry Potter, so do you know why Rowling designed such an ending?

From an objective point of view, Harry more than a decade ago was just a small baby, and Voldemort was an adult dark wizard
Even though Harry had grown into a good wizard more than a decade later, he was still an underage child
Why could Harry, who seemed to be weak, repeatedly defeat the Great Demon Lord Voldemort?
Judging from Rowling's definition of the entire Harry Potter series, voldemort could not beat Harry for one reason, that is, love
First of all, Voldemort was not a child born of love, so he did not know what love was, let alone how powerful love could be
Friends who have seen the original book know that Voldemort is a descendant of Slytherin
Voldemort's mother, Melope, was the youngest daughter of the Gaunt family, and as a young woman, she was attracted to her neighbor, Young Master Riddle
Riddle is dignified, personable and rich, but unfortunately, Riddle already has a favorite object and rejects Merop's confession
Reluctantly, Meropp creates a charm agent and uses it on Riddle to make Riddle "fall in love" with himself
Melop elopes with Riddle, and the two have a love crystal, later Voldemort
The IQ of women in love is always unsatisfactory, and after pregnancy, Meropp thinks that since the two people already have children, Riddle is naturally a little sincere about himself
As a result, Merlop decided not to use ecstasy on Riddle
Riddle instantly woke up after stopping the drug, and he completely collapsed in the face of the crazy woman in front of him
Leaving the pregnant Meroppe behind, Riddle returned home alone
The abandoned Melope had to give birth to the child alone at the gate of the orphanage, and Merlop died shortly after Voldemort was born
The orphanage's staff adopted Voldemort, but because voldemort had no wizarding talent, the other children in the orphanage rejected him
Therefore, from childhood to adulthood, Voldemort did not feel the family love from his father and mother
I have never felt the friendship of my peers
Even though Voldemort, who had been brought into Hogwarts by Dumbledore and sorted into Slytherin, did not make a close friend
Voldemort always looked down on everyone with a lofty posture, and even the Death Eaters who were loyal to him were only his own little followers in Voldemort's eyes
Therefore, Voldemort had never felt true love
Second, the ancient love spell that Lily had inspired in Harry
Voldemort listened to snape's prophecy and decided that Potter, the son of Jaime and Lily, was the legendary son of a prophecy capable of defeating him
Voldemort desperately tried to get rid of Harry, and James and Lily protected Harry with death
Lily, in particular, gave her life when she was dying, and Lily used her body to block harry's presence
Lily's actions triggered an ancient spell of love that prevented wizards as powerful as Voldemort from harming Harry and leaving only a scar on Harry's head
Finally, let's talk about an external condition, that is, the Old Wand
At first, the Old Wand was in Dumbledore's hands, and Voldemort sent Malfoy to assassinate Dumbledore, but Malfoy, who was struggling inside, could not get his hands on it
So Snape obeyed Dumbledore's arrangement and killed Dumbledore in place of Malfoy
Voldemort mistakenly believed that after killing Dumbledore, Snape became the new owner of the Elder Wand, and finally ended Snape with Nagini, making himself the master of the Elder Wand
But what Voldemort didn't know was that Malfoy had disarmed Dumbledore's wand before Snape killed Dumbledore
The real owner of the Old Wand was Malfoy, and Harry defeated Malfoy, so the Elder Wand eventually obeyed Harry
When Voldemort used the Elder Wand against Harry, the Elder Wand did not kill its master, directly bouncing the spell back onto Voldemort
So, do you know the real reason why Voldemort couldn't defeat Harry?
