Harry Potter is just a boy but has courage beyond his years. From the
first book, when he has to find the sorcerer’s stone, he undertakes an
adventure he never dreams about, facing the three-headed dog, the weeds,
the chess game. Admittedly, he didn’t fully understand the dangers he
took, but he pushed ahead.
By the second book, his understanding is a little clearer, thanks to
the mentors that step in. But I don’t think he truly sees the
intricacies of the dangers he’s in until he meets Sirius. He sees
everything isn’t as black and white as it seems, and by the time he
meets Dolores Umbridge, he understands the number of people he can trust
is very limited. But that doesn’t stop him from going to the Ministry
of Magic or following Dumbledore in the pursuit of the horcruxes or
fighting Bellatrix and the Malfoys.
Where does he get his courage?
Example! From his mother who gave up her life to save his, to Sirius,
to the Weasleys, to Dumbledore. Each of these show him what courage
means while giving him the support he needs to match their bravery. He
can only go the places he goes because of the love he receives from Ron,
Hermione and the others. When that’s taken away—Ron turning on him
after his name comes out of the Goblet of Fire, during the camping
trip—he struggles and wavers. He continues forward, because he has the
courage, and he knows what’s right, but only finds true success when he
has the strength of his friends behind him.
