Melbourne: How do some people turn killers and have no guilt about their actions? That's due to a brain mechanism that justifies killings, says a study.

The neural mechanisms that are typically implicated with harming others become less active when the violence against a particular group is seen as justified, the study found.

"The findings show that when a person is responsible for what they see as justified or unjustified violence, they will have different feelings of guilt associated with that," said lead researcher Pascal Molenberghs from Monash University.

"For the first time, we can see how this guilt relates to specific brain activation," he said.

Participants in the study played video games in which they imagined themselves to be shooting innocent civilians (unjustified violence) or enemy soldiers (justified violence).

Their brain activity was recorded via functional magnetic resonance imaging (fMRI) while they played.

Molenberghs said the results provided important insights into how people in certain situations, such as war, are able to commit extreme violence against others.

"When participants imagined themselves shooting civilians compared to soldiers, greater activation was found in the lateral orbitofrontal cortex (OFC), an important brain area involved in making moral decisions," Molenberghs said."The more guilt participants felt about shooting civilians, the greater the response in the lateral OFC.

"When shooting enemy soldiers, no activation was seen in lateral OFC," he noted.

The results show that the neural mechanisms that are typically implicated with harming others become less active when the violence against a particular group is seen as justified, the study found. It was published in the journal Social Cognitive and Affective Neuroscience.
