Deeply flawed?
You are right. Deeply flawed makes it sound fatal to his greatness, and I agree that sounds more negative and damning that I meant it to be.
If you read my post, you can probably agree I do not, in any way, view his flaws as fatal, quite the opposite, he soared to greater heights with deeper flaws and obstacles in his way than most men at his station in life, which highlights what a savant in many ways that he was. And it didn’t come easy to him, it is widely thought that he had dyslexia, and he had to work far harder than many other people to overcome its detrimental effects in his learning.
We are all flawed, all of us. I view flaws as lead weights dragging you underwater, while your positive points provide buoyancy that keep you on the surface. For most of us, our flaws don’t overpower the positives and drag us under, which is good, because most of us have enough positives to offset them.
It is accepted that Patton had some psychological difficulties later in his life that today are seen as characteristic of a severe brain injury, of which he suffered a serious one playing polo when he suffered a severe concussion (kicked in the head by a horse, IIRC)
This made him emotionally and verbally fragile, often unable to control his anger or sorrow, culminating with the “slapping incident” which would have destroyed many men’s careers.
The fact that he was so brilliant in so many other areas is a testament to what an amazing man he was.
