The purpose of this crime is said to be enact a curse; however, in another theory, while the victim of Ikihadadachi described in the previous section was still alive when his/her skin was hurt, the victim of shinihadadachi was injured to death, therefore it is equivalent to a charge of injury resulting in death.
その目的は何らかの呪的行為にあるとされるが、また前項の生膚断が肌を傷つけられた被害者がまだ生存しているのに対し、被害者を傷つけて死に至らしめる、所謂傷害致死罪に相当するとの説もある
