I don't want to get inside the mind of a criminal or stare into the BK abyss, but I'm curious whether anybody here has any insight into what he might be thinking as he sits in jail. I imagine he has a cell to himself, for his own protection.
Here's someone who, while not fantastically successful, did enjoy certain freedoms up until a few years ago and accomplished some things few people do -- the Master's, the PhD program. He wasn't maybe collecting accolades or winning friends, but he was living, moving and having being. Star gazing, tailgating, veganating...
So what's he doing now?
Push-ups?
Running in place?
Saving up to call home? Every day and twice on Sunday?
Does he have any portion of discovery to pour through?
Does he?
Does he read?
Does he interact?
Does he imagine being exonerated?
Does he have actual aspirations? Regrets? Does he have the capacity to feel bad?
Is he bored? Angry?
Does he feel detached from his current reality?
Does he write letters? Motions? Manifestos? A diary?
Does he relive his crimes?
Is he plotting future ones?
Is he mad at himself, for perceived missteps?
Is he pleased with himself? Finding fault in others?
Does he really think he'll ever be out?
Does he care?
Does he stare at the wall?
Does the wall stare back?
If he had it to do all over again, would he...
...do it differently? Or.... not do it at all? Or do it....worse?

Good musings and important to the potential "backstory" of BK,
@Megnut!
Bouncing off those questions, I personally don't think if he had it to do all over again, he would do anything differently, and he got what he wanted: free lodging and a deep dodge away from RL, in perpetuity. And he doesn't care if he ever gets out because....
JOO (a lot of JOO

):
He's right where he wants to be and is just fine in his self-imposed isolation from society with all the creature comforts prison and the justice system offers. He's probably much more comfortable there even if he's a little bored from not being able to do whatever the heck he wants on the internet, lurk around & stalk women, go to school, go for runs, and star gaze.
He was more than ready to opt out of RL in a blaze of depraved criminal glory, and go down in the annals of crime history as the quadruple murderer who lined everything up in advance. To obfuscate justice for the victims and their loved ones, terrorize young people attending college and their communities and society at large (especially young, successful, popular and well adjusted and attractive women - everything he isn't and couldn't be involved with except as a lurker/stalker through SM) and make it all truly difficult and super complex for the Moscow LE, state of ID and federal legal systems (remembering the FBI was called in to assist LE fairly quickly) to process.
I may be in the minority, but I've always thought he got caught on purpose. Through planted evidence [e.g., a smidgen of touch DNA on the sheath he left under one of the bodies of his victims] or making sure his car was seen on camera or his cellphone pinged in places near the murders [creating hundreds of hours of painstaking work for LE to sift through video footage and cell tower data] that would take awhile to lead back to him, and even then it would just be circumstantial evidence.
I think he was gleeful about all the things he did to make the investigation complex as all get out, and was primarily/ultimately desperately seeking notoriety/being an infamous criminal mastermind, which was a huge motivator for him, following in the footsteps of other killers he studied and likely idolized.
I think he got a lot of gratification from playing cat & mouse with LE, leaving lots of bread crumbs that would create uncertainty regarding the perpetrator, eventually leading to a SODDI/TODDI defense and never a whisper of guilt/involvement uttered from his lips. He stood silent in court when the charges against him were read and continues, AFAIK, to hope to be exonerated as he said through his 1st lawyer in PA when he was arrested and being held in jail. No declarations from him of innocence or wanting to be free from imprisonment, or desire to expedite the legal process, etc. I think he's happy to bide his time in prison waiting to see how things turn out for him with the public defenders battling it out with the state prosecutors, and it's all free, so no skin off his back, there is such a thing as a free lunch after all.
I think he fashioned himself as a victim of RL due to his issues with not being adept at functioning well in society and his criminal tendencies. Notwithstanding the RL support system he had in place from his family, professors, maybe some mentors through jobs he had, peeps on SM (no RL friends in recent years AFAIK), and medical professionals throughout the years of his youth and young adulthood.
I think he was a ticking time bomb as an independent adult away from home/his support system for the first time, attending a graduate program in person (having gone to school locally and remotely for several years prior, AFAIK) across the country. His release from the torments of his RL dysfunction was enacting his diabolical plan to murder Moscow college student(s), which was a long time in the making, to keep him from having to go on in RL where he wasn't making it, except in his mind as a criminal mastermind.
Depravity doesn't even begin to cover the horrific crimes and devastation he wrought, and with no remorse, so he could parachute into a soft landing in the prison system from the hard knocks of his RL. An outboarded, twisted version of 'suicide by cop', but played out over the long run, cuz he's never getting out of prison. But he's got all the details of what he did and his RL victimhood to keep him company during the long hours sitting in his cell between meeting with his free public defense team and easting and sleeping. Not so bad of a setup if you're not down for RL.
All my long winded JMO, again...
I'm really looking forward to his trial coming up soon, and justice for Kaylee, Maddie, Xana, and Ethan and their loved ones!!
