I will add my IMHO spiritual answer
Rape is the forcing of a soul tie between the rapist and the victim, the 2 are forced to become one. During this time the guilt of the sexual sins of the rapist is forced onto the victim, Usually rape victims feel ashamed, even of their own body - this is the guilt that has been transferred, which frees the rapist from that guilt and shame.
This is different then what we call ‘date rape’ which the victim is usually the one who caused the rape. It is the use of spiritual power to free the person raped of sexual guilt, as it is transferred to the one doing the raping, but that person is spiritually controlled by the other as they have submitted to them. In this way the one raped can free themselves as the other person bears the weight of the sin.
