I don't get the sense that BR was abused. He may have had a whacko mother who was hell-bent on fame for his sister, and he may have had a father who was not around as much as he would have wanted, but I have seen nothing that makes me feel he was abused, sexually or otherwise.
On the other had, there is physical PROOF JB suffered abuse, both the night she died and on at least one other occasion.
Being an "odd" kid (which by some accounts he was), having Asberger's Syndrome (which some feel he did/does) and having an overbearing mother and grandmother doesn't make you a killer.
Having a bad temper, lashing out in anger in an irrevocable burst of rage COULD make you a killer. Not a career criminal, but someone who was responsible for the death of a sibling in what was an escalating cascade of events that began with sexual exploration and painful penetration, followed by a silencing bash on the head. Mom and Dad clean it up. That pretty much spells it out for me.

I agree with what you're saying, but I keep going back to the fact that LE never considered BR a suspect in any way once they completed their investigation of him. And, others have pointed out here (and I agree), that LE would not have spent all of these years and man-hours investigating this murder if they had any evidence of any kind that it was a nine year old kid who was ultimately responsible.
You say there is no proof BR was abused, but I see all kinds of red flags that he was abused in some way. Bed wetting, smearing his own waste on the walls, these are common signs of some form of abuse...whether it's sexual or not (maybe it was emotional abuse...or neglect).
I will never quite believe, absent a confession, that BR was responsible for the death of JonBenet. The circumstances of her death, along with the staging, are adult in nature IMO. I have a really hard time visualizing either BR or PR sexually molesting JonBenet. However, to me, JR is creepy. PR was absolutely a player in the cover up, but I still truly believe JR is the principal in this crime. It's a gut feeling I get when I watch him on camera.
Absent any real evidence against anyone in particular, I tend to lean towards what logic tells me. And logic in this case tells me that there are fathers that molest their daughters. And that sometimes that results in that child ending up hurt.....or dead.
One last thought for you to consider. One of JonBenet's teachers said that JB became very clingy with her mother shortly before she died, which was out of character for her. What was going on that made that so? If she was so frightened of her mother, why would she cling to her?
I can't see JB covering for BR if he was responsible for the prior/ongoing abuse, but I can definitely see her covering up for daddy. Think about your relationship with your father at JB's age. I would have gone to the ends of the earth and back for my dad, but I wouldn't have walked across the street for my older brother.
I try to put this in perspective based on my own life experience. It's all my opinion only.
