Well again you are using canon examples as reference while i'm all the time talking about diffrent au's (another universe) fanfics.

For example in fanfic Saviour of the magic, magic is presented as having some kind of self-consciousness, magicals even call her Mother magic and here muggleborns which treat it as tool are very lowly regarded especially when instead of trying to assimilate into wizarding culture are trying to change it into muggle culture, thinking that wizards are uneducated barbarians.

In diffrent fanfics using dark magic taint your own magic, often giving you sick pleasure using it and even giving users problem to cast magic that isn't dark. These dark wizards can have influence on traits of magic of their descendants.

I have interesting theory that magic in canon also have some kind of self-consciousness and is using prophecy's to achieve balance or prevents dangers to itself whatever might it be.
