When rational motives are conspicuous (for example, when a man kills for personal gain) or when the irrational motives are accompanied by delusions or hallucinations (for example, a paranoid patient who kills his fantasied persecutor), the situation presents little problem to the psychiatrist.
Zentzuzko eragileak nabarmenak direnean (adibidez, beretzako irabaziak lortzeko hiltzen duen gizona) edo eragile irrazionalak lilura edo haluzinazioekin batera ematen direnean (adibidez, bere balizko segitzailea hiltzen duen gaixo paranoikoa), egoera aski argia da psikiatrarentzat.
