Is there anything you doubt the brothers on?

I’ve read and watched so much about this case now. I fully believe that they were abused to the extent they were, I believe they were in fear for their lives and really believed their parents could and would harm them, and I believe that the crime was not pre-meditated in that the guns were bought only a few days before the killings and the crime scene being so messy points to a frantic, highly emotional killing.

One thing I think they maybe weren’t fully truthful about for the trial (and I understand why they weren’t) was that there was definitely an element of rage/hatred that played into what they did and how they did it. I think those feelings did make them wish/want their parents dead/gone. I don’t blame them at all for feeling that way either. I think the rage especially shows in the final shot to Kitty too. I think maybe that’s why it bothered Lyle so much after the murders. It was a moment of uncharacteristic rage/hatred on his part, like he was overcome by it in the moment, and it haunted him after because of that.

I’m curious to know what you guys think.
