> Fault is a tricky term in this context.
I was talking more from a legal perspective -- where a party's actions or negligence is the direct cause or a significant contributing factor to an accident.

I live it every day.
> Even their advantages
There are no advantages. I have yet to see something that a person with ADHD can do that a person without ADHD cannot do that can be solely attributed to ADHD and no other factors.
So, I am going to cut straight to the heart of this argument. Do you believe in free will or not? I do not. At least not in a complete sense of the idea; however, I am not sure society can function without some level of belief in free will.
If a person with ADHD kills another person in a vehicular accident, should they be automatically free of punishment because it's not their fault? If not, then that is perhaps even more morbid. It's like saying, "We know it's not your fault, but here is some punishment anyway."
As for evolution, countless variants of countless species on this planet have been lost with the sands of time due to natural selection. Their inability to adapt to the environment around them was not their fault, but as evolution shows us -- too bad. And honestly, that mirrors my experiences with life with ADHD. It sucks, it's not fair, but too bad. The universe owes no one anything.
