My dear friend, even though I can fully understand your perception of the whole incident and fully agree on how inappropriate physical abuse is no matter what, in the quality of toxic people and especially pathological narcisists education activist, I need to say that I do feel for Will Smith more than you can even imagine...
It is heartbreaking to witness how manipulated he is by his narcissistic wife. In reality, she is the perpetrator! It's just that she's too smart and subtle to show her true colors openly, and brilliantly and cruelly uses her husband as a flying monkey to do the shitty job on her behalf.
Something is sure here: Will Smith has never recovered from his toxic family of origin system. Attachment theory explains very well why he found himself in this marriage in particular. History is simply repeating itself: we are attracted to what we are familiar with.
And a very telling red flag about how manipulative Jada is would be how Will Smith defended her wholeheartedly when she cheated on him and publicly talked about it when she invited him on her show... Rudeness and lack of empathy under the cover of openness and self-confidence. It speaks volumes about the "Cognitive Dissonance" level and how blinded Will Smith is, sadly enough.
I once watched a session of Jada's show where her daughter Willow shared some very vulnerable episodes and serious mental health issues. Her mother's reaction was so COLD that it was too obvious to me she can only be a narcissist. Zero empathy literally! I HATE all the harm she's been inflicting on Smith's family members... She's a horrible person only good on paper, and that's how most of abusers do life!
