The home was acting in self defense, tge bad guys fired at him first. By moving off of the porch he was drawing fire away from his home and family.
The charges will not stick
You gotta work on improving your reading comprehension skills. You apparently missed this earlier, even though you copied it into one of your comments:
The security video shows a lot more than the printed story provides. For instance, after leaving the relative safety of his house to challenge the thieves, certainly not inappropriate for someone with some backbone, he takes concealment (and likely good cover) behind an auto in the driveway when the shooting starts. However, he then abandons that cover to advance on the crooks, appearing to unnecessarily go on the offensive, inconsistent with an act of self-defense.
You also missed, or have forgotten, the fact that “the home” (as you now identify him) was actually charged with reckless endangerment (presumably for wrongfully endangering his neighbors by his blind, wild shooting at nothing in particular). He was not charged with ADW on the bad guys, though he certainly could have been, based solely upon the last shot or two he fired.
