The present dataset consists of cross-sectional survey data collected from general community participants by undergraduate psychology students. The study assessed demographic variables, antagonistic traits (psychopathy, narcissism, Machiavellianism, sadism), self-control, guilt, shame, moral disengagement, moral identity, and materialism, as well as participants’ willingness to commit a crime if all crimes were legal for a day. The data collection aimed to replicate and extend the study by Meldrum et al. (2021), which examined individuals’ willingness to engage in criminal acts—including murder—in the absence of legal controls. In addition to this general question, we included a new questionnaire assessing participants’ likelihood of committing specific types of crimes (e.g., theft, murder, kidnapping, sexual offenses) under such conditions. Data collection was approved by the Ethics Review Board of the Tilburg School of Social and Behavioral Sciences (TSB_RP807).

The variable Q5_Others (containing additional self-reported information about past criminal behavior) was deleted from the dataset because it potentially included identifying information.
