In addition to an ideal victim, there must be an ideal perpetrator for a crime to be considered ideal. The ideal attacker does not know their victim and is a completely non-sympathetic figure- one who is considered sub-human, an individual lacking morals. An attacker that knows their victim is not considered an ideal attacker, nor is someone who seems morally ordinary. Cases of intimate partner violence are not considered ideal because the victim knows their attacker. Husbands and wives are not ideal victims or perpetrators because they are intimately familiar with each other.
