I realize that, but not all DV is with the intent to kill, especially a child. I would think if one was hurt badly enough to say that the father tried to kill him, then he would need medical attention. If he hit one of his kids in the face with a fist, then yes, that's abuse. But it would not be classified as an intent to kill, as far as I know.
I was slapped in the face, whipped with a belt, and spanked on my bottom many times growing up, but I'm quite sure my parents never intended to kill me. That was in the days when physical punishment was acceptable.
All I am saying is, maybe he does have a history of DV, and may have taken his anger out on his kids sometimes. But it's a big leap from losing your temper and striking a child to literally wanting to kill them, KWIM?
