FWIW, I’ve been reading quite a few different articles about contributing factors to this incident. Mr. Holmes seemed to be intellectualy adept but socially inept and was failing in his young adulthood. This lead to him dropping out of a PhD program and delving into illicit activity (ie pornography addiction, bombmaking, stockpiling high powered weapons & ammo). I don’t want to get into an argument based in relativism but whether he is/was mentally ill or has a personality disorder, etc this is the primary reason that lead him to do what he did.
People that actually knew Holmes report that he was frustrated with how his life was turning out, quite common among males in their 20’s (I should know I just turned 30). We hate to reflect upon our failures and are often to prideful to see things clearly as well as strive to rectify our issues. If one becomes severely depressed they can spiral down until all they have is anger, hatred, and a vast slew of negative emotions. They may come to desire a release and unfortunately in this instance the outlet was this horrific occurance.
I’ll leave a link to an article I’ve come across that seems to tell as much as anything I’ve read about Mr. Holmes thus far:
