You are saying that killing someone from inattention is the same as killing someone from drunk driving.
I don't think you understand those are the same argument and that you are inconsistent.
I did not say that. I said the ACTS weren't the same. Killing someone while defending yourself is a different act than premeditated murder.
I would even argue the results AREN'T the same: in one, an innocent person is killed; in the other, a guilty person.

"Inattention" can mean many things. Stick with the antihistamine analogy: killing someone by driving impaired after taking antihistamines is the same as doing so while drunk.
