Which of these additions are required varies according to the severity of the sin, whether it was done willfully, in error, or under duress, whether it was against God alone or also against a fellow person, and whether the Temple service and ordained law courts are in existence or not.
Depending on how severe the sin is, whether it was committed intentionally or by mistake, against God alone or another person, and considering if Temple rituals and ordained courts are active, different additions may be required.
