How much money each party gets is up the the courts. There is no shame in suing for damages after someone has injured you. That’s what civil suits are for.
I agree that the harmful actions of each party will be examined in the legal reckoning.
This will be controversial- prepare yourself:
Just as “Let’s get rid of her”. “Let Ruth do it” can admit a wide range of interpretations, “Finish the bastard” has interpretations other than “I know MB is on the edge of a psychological breakdown, let’s deliberately push him over the edge.”
Texting to MHG ‘I’m going to get her banned from USEF for life’, on the other hand, is less ambiguous.
I think the jury determined he was not legally responsible for shooting her due to his insanity. I do not think they needed to determine the exact breakdown as to her quantitative role on “causing” the insanity, as distinct from his childhood abuse, his CPTSD and the other psychological stressors on him at the time, both financial and personal.
