This is partially due to the ‘War on Terror’ which has been raging for more than two decades and shows no sign of slowing down. The need for practical application of the research has made that the field has become relatively one sided and occupied with ‘the other’. This research seeks to bridge that gap. To this extent this research focuses on the universal nature of radicalization and justification for violence. It does so by comparing and contrasting two very different groups. On one side Muslim extremists and on the other Western war criminals. The research was conducted applying thematic analysis to six autobiographies written by the violent individuals. Several universal themes were found which all lead to the application and justification of violence towards a civilian population. However, notable differences were also found which again emphasizes the complex nature of radicalization research. Overall, this paper shows that there are themes and perspectives which have not been touched upon by contemporary research and urges for more exploration of the topic. This paper, with its exploratory nature, aims to be the foundation on which future research can be performed.Show less
