It strikes me that your belief that someone is a moron or an asshole if they fail to leave earlier might be coming from a place of not understanding ADHD. You say "as a human being" which drastically oversimplifies and understates the irratic nature of the mind of someone suffering with the condition.

As someone who has ADHD, i believe i can say, with a fairly high degree of confidence, that you do not suffer with the condition. Or that if you do, you have found a good coping mechanism for issues with timekeeping. Or at the very least timekeeping is not one of the aspects of ADHD that affects you.

But to call someone an asshole or a moron because you dont understand how their mind works and you seem to think what works for one, works for all, is the most moronic and asshole-like thing that you can do.

I put it to you, that you have no idea what you are talking about, and despite the fact that alot of people mistake normal aspects of various personalities with full blown ADHD, and thusly self diagnose, in error, that your opinion on the simplicity of changing ones behaviour on a dime has no place on an ADHD forum.
