The Unforgivable Curses are three of the most powerful and sinister spells known to the wizarding world. They are considered to be the strongest known Dark spells and are strictly forbidden by the Ministry of Magic.
- The Cruciatus Curse (Crucio): This curse inflicts excruciating pain on the victim. The caster can inflict this pain at will and prolong it as they please.
- The Imperius Curse (Imperio): This curse allows the caster to completely control the victim's actions. It can be used to force the victim to perform any action, no matter how heinous.
- The Killing Curse (Avada Kedavra): This curse instantly kills the victim. It is considered to be the most unforgivable of the three, as it leaves no room for redemption.
These curses are considered unforgivable because they represent the darkest aspects of magic and are used for malicious purposes. They are forbidden because any reason for casting them would be to commit a terrible act.
