Purity is measured in a scale that defines how pure someone is, ranging from 0 to 1, with 0 being completely impure and 1 being perfectly pure. Purity is defined as how much and how often said person believes that their actions are right.
Morals in purity are relative to the person whose purity is being measured, not to society. If a person effects an action which they believe is moral, it is considered a pure action even if it is considered to be morally wrong by others. People can be considered more pure regardless of how horrible their actions may be, as long as they believe that they are doing the right thing.
Stealing money is often considered an impure action, but its purity depends on the motive behind it.
- If someone steals money they don't need knowing that their actions are wrong, then the trait is considered impure.
- If someone steals money they need while simultaneously believing that stealing is wrong, then the trait is considered somewhat pure.
- If someone steals money believing that it is rightfully theirs, then the trait is considered pure.
- Most people will be somewhere in between 0 and 1, but not at exactly 0 or 1. Only characters involved with the Perfection Curse or the Preservation Curse may have these levels of purity.
- Purity is not a fully intangible concept in the Malice universe, for it can be measured through White Light.
- The system of Purity isn't necessarily right or wrong. It is up to people to decide whether they believe in it or not. Ironically, having disbelief in the system of Purity is considered a pure trait, as long as the person truly disagrees with the Purity system.
