That's not to say they don't present a disturbing window into BK's emotional state at the time and lead to many questions re what may have turned out differently had he somehow been able to access effective help.
I would venture to guess that there are many things in BK’s past and history which would/could present a disturbing window into BK’s emotional state (not merely this time, but MANY times over). I would further surmise that the P’s investigatory team unearthed more than sufficient evidence of possible trauma suffered throughout his life and possible evidence of more nefarious acts committed by the suspect. This sets the basis, foundation, and ground rules for the case.
Most all people deal with issues in life, which invariable include similar circumstances. It’s part of the normal human condition. Yet, they do not proceed to stalk, plan, and kill any human beings. Everyone is physiologically and biologically different. Therefore, everyone processes life differently, based on seemingly infinite factors. Somehow, along the journey, BK suffered a critical breakdown resulting in a life changing period. He masked it very well, and appeared to overcome any issues which were noticeable to friends and family (No one else can discern the cracks in his veneer, save for him). In successfully FOOLING them, he grew much more confident and shocking bold in the time leading up to the murders. He celebrated any cunning acts of prowess and capability, no matter how insignificant. That is what sociopaths do best. Fool the masses. Give them an inch…
He will be in full “acting - mode” during the trial for the most part. Feigning great personal suffering and injustice, but NOT in regards to the homicides. Au contraire. He will continue to profess his innocence (another socio trait), until his dying breath. No, he won’t link or associate anything which may implicate him concerning these homicides. The four he continually, vehemently, and emphatically maintains he didn’t and couldn’t have committed (after all, he was STAR-GAZING Y’ALL
️ ). He believes everyone else just fell off the turnip truck. He will be playing the full victim (to the point of over-acting) a broken justice system, over-zealous, under-qualified law enforcement, and a city intent on convicting someone for the crimes. None of this is TRUE nor FACTUAL. The opportunity to defend himself is only by proxy of fate and circumstance, as the victims can no longer speak on their own behalf. He made sure of that. But that will not stop him from following his own script and effectively beating the dead horse into the ground.
This is all just my own hypothetical opinion, but everytime I watch the clip of him entering the courtroom - shoulders slouched, trying his best to make himself smaller to the point of invisible — I want to throw up. It’s not working dude, we SEE you. He continually strives to appear more vulnerable, passive, and meek to the point of incapable of committing such acts. He plays the innocent lamb being paraded across the media and marked for slaughter. That is the narcissist in him. He still believes he is the most clever person in the room, and will “play” everyone to the HILT to win his endgame. I believe the 12 people chosen to carry this through will be MUCH smarter than he understands. They will see through the facade and come to the right conclusion based upon the evidence. Justice will be served (cold, as it always should be!).
