If it's an enviromental thing, family dynamics, childhood upbringing with abuse, why did his sister didn't become a monster too? Seriously, I ask myself everyday, what went wrong with that guy, who would torture kittens and post on youtube and nobody in his family did an intervention? If I was his sister, I would hand him out to the authorities and health system and if nothing helped would cut ties forever.
I think he must have hurt a lot of people in that family too, we even don't know if he killed his pets or what else he did... but still they should have done something, if they knew Luka was a ticking bomb and a danger to society, if they were aware of the kitten killing videos, they should have warned the police. JMO!!!!
I wanted to respond to this because it sounds like you came from a good family Donyale.
Myself, as a poster child for a dysfunctional family, not all of us turn out monsters. I am the oldest of four, my paranoid schizo father wreaked all types of havoc until my very young mother chose to flee from him one day while he was at work.
One of my sisters is histrionic, but she functions (just very egotistical--haha);
my brother is in prison on 21 felony drug charges--I believe he got a bit more of my dad's genetics and as a male may have turned outward as a solution to his mental issues; myself, I have a few things wrong mentally in that I have pretty high anxiety, but I turned inward and mainly dealt with depression and some other things that are undiagnosed as yet. I went to grad school, got my MBA, and work high level in a company making six figures. I am female and I believe the fact that society allows females to express emotions and be more nurturing, etc, allowed me to come out better than my brother in the end. Despite background, we still choose our path. My brother likes to blame others for his situation, and I never did that.
Not all abuse is going to mess everyone up equally or in the same way, even in the same family, we are wired differently and have different coping mechanisms.
As for what you said about dumping LRM in the system and never speaking to him if he didn't improve, having the brother I do, I agree to an extent, he's done things to me that are terrible (broke into my house and stole most of my expensive possessions to pay for his drugs, for example). However, if I knew there WAS a way to help him by my being present, I would in a heartbeat. What I find odd (and maybe it's going on in the background and I just don't see it) is that LRM's family seems absent other than speaking ill of him to the press (calling him a nutjob). If this were my brother, no matter how messed up, I would be there to assist the lawyers and psychiatrists in getting what they needed. That's how I feel family unconditionally loves you. I think part of this lack of support system speaks volumes to things he says happened in his childhood. I could be wrong, though.
