Unless the dad knew of the other guy's history and acted the way he did in light of it, I don't think it's relevant when considering the level of force he used to counter whatever force was presented to him. I don't think the dad knew it.

With a few significant exceptions (like in your home), you generally have a duty to retreat and meet force only with like force.

I think.

To meet force with only like force is a good way to get yourself killed. And I know in Texas, that is not the case.
