A mental disorder or mental illness is a psychological pattern or anomaly, potentially reflected in behavior, that is generally associated with distress or disability, and which is not considered part of normal development in a person's culture.
And those guys were Chechens, so they were probably Sunni Muslims either Shafi or Hanafi schools of thought. If that is correct they are mentally ill. On other hand a minority of Chechens follow Salafism, for which those practices are a duty to their society, so they were not mentally ill in the first place. What I can say for sure is that there isn't enough data for now.
I just tend to believe that we should require more from our ethically superior civilisation (this actually can be measured) than a barbarians repost that is "kill the traitor/infidel/murderer".
