[Spurious pity--lethal consequences: how helpers turn into offenders].

This study gives a general view of 40 cases of killing series by members of staff in health care professions in hospitals and homes. The main issue of the analyses are the nine killing series in the German language area. For the investigation legal documents concerning specific characteristics of victims, site of crime and offenders were evaluated. The respective fields of work were investigated concerning the working climate, the position of the offenders in their working group, conflicts in the work place and the handling of the first intern hints to suspective behaviour. It is derives from the case-by-case analyses if there are any preliminary warnings and if there are any commonalities with regard to the victims, the offenders and the respective fields of activity. Personal sensitivities, working conditions and permanent confrontation with human sufferings can be interlaced with each other in that way that the superficial motivation to help is abysmally reversed. In this repect a term of compassion, which confounds real sympathy and self-pity, is essential.
