I guess no one really pays attention to Filch, becaus ein the books and movies he’s rlly just… there…JK maybe should have made a twist or conclusion why, I guess..

I think that no one really knew he was a squib, maybe they just thought he was bad at magic. He really wanted to keep his Kwickspell course a secret, remember?

Dumbledore probably felt sorry for Filch, and gave him a job out of pity

I wonder if Dumbledore didn’t give him a few items to ease his chores, and obscure his squib status.

I always think him is a very unfortunate and sad character, his position will always be reminding him that he is a squib and will never be a wizard. Though I really dislike the fact that he supports Umbridge.

I think Argus is very much like Dumbledore, Hagrid, Voldemort, and Harry. Hogwarts is his home, his kingdom. Dumbledore’s love of knowledge and tragic life made Hogwarts the perfect place for him. Hagrid, an orphaned outcast, found a place to fit in at Hogwarts. Voldemort, an evil ambitious meglomaniac orphan, found his home – his kingdom – in the place he found his true gifts, Hogwarts. Harry, the same as Voldemort only his heart was right and Harry wasn’t an evil git. Argus, in my opinion, desired to be magical and so he dedicated himself to the institution that shaped all the best witches and wizards. His own desire to be what he couldn’t be made him all the more dedicated to his non-magical tasks (cleaning, keeping the rules, etc). His continued lack of any magical qualities created in him a manic frustration that expressed itself in his hostile behavior towards the students who he watched become what he could never be. He had the desire to be great but it just wasn’t within him. That frustration created the pitiable creature we see in the books. Dumbledore may have kept him in hopes that he would some day come to terms with his own short comings, or maybe Dumbledore kept him because it is often useful to have an overzealous employee. You’ve got to admit that the man was determined to mop and clean and kept an eye out on every student that got out of line.

Dumbledore is a great man, he trusts people who deserve his trust, but sometimes, he trusts those who fail him without really knowing such. But still, he is a great man! Filch, in my opinion is a rule-follower, sometimes I like that, but sometimes I feel that it is too much. Also, I find myself feeling sorry for him.
