I don't think anyone can argue with:
- the guy went outside because the burglars were "getting away" with "a bag of loot", not because they were threatening him or his neighbour or anyone's property.
- the guy went outside with the intention of killing them.

in civilized countries this would be premeditated murder, not manslaughter or self-defense. Civilization is relatively new to Texas and to the US in general: it is a very young state and it isn't long since it was an untamed frontier. It's standard that countries like that have less respect for the rule of law. Vigilante justice is commonplace in such countries: research for example the Texas Rangers, Hamas or Mapogo a Mathamaga.

Texas has to decide whether it wants to take another step towards civilization, but I suspect Texans are perfectly happy with the way it is.
