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. But murderers who seem rational, coherent, and controlled, and yet whose homicidal acts have a bizarre, apparently senseless quality, pose a difficult problem, if courtroom disagreements and contradictory reports about the same offender are an index.
