I understand what you're saying, but experience has taught me that many many many people use whatever the thing is (trauma, ADHD, whatever) as an excuse to act however they want whenever they want. It becomes a crutch, or a security blanket to let them just be okay with wallowing in the negativity and externalizing every problem.
There has to be a happy medium. I have some neuro issues, and yet I understand that while I may not be able to control the issues themselves, only me is responsible for my own actions. That is lacking in many folks who share my diagnoses. We dropped the ball somewhere and I don't know where, to be honest.
