Dark Magic

A sort of magic that has been frowned upon by many, dark magic is a corrupting and dangerous magic that can easily cause people harm. It's practitioners tend to be, or become, blood-thirsty monsters who take pleasure in cruelty towards others.

The people most well known for using it are often also seen as villains, such as Voldemort or Bellatrix Lestrange.

Ron Weasle y nearly fell into the trap of using it and become a vile monster, but he burnt his dark magic book because he realised it's harm to him and other people. However, many of his other selves, such as Ravenclaw Ron, have gone down the dark path of this magic and killed hundreds.

There are many people with jobs to break down dark magic, such as curse breakers like Bill Weasley. Ron has broken down some dark magic before, such as horcruxes. This sort of work is dangerous, which is the reason that Dumbledore gave him a dark-magic protecting poach to keep the horcruxes he found in. As well as this, many dark magic books and curses are simply banned due to how harmful they are, such as the tome that Victor Burke gave to Ron.

Many peices of dark magic require immense power, such as the dark mark.

Many forms of dark magic are outright banned in Britain and other countries. For example, Necromancy. It is banned in the entire wizarding world, seen as a taboo and an insult to life. Necromancy is the revival of the dead. Many dark lords, such as Voldemort, have commited necromancy crimes, such as creating inferi.
