It's arguable, but several details are missing:
- Was the robber who was shot already dying?
- Was the robber capable of further posing a threat to the man?
- Did the robber give him reason to believe he was going to try to attack him while on the ground?
You could likewise argue something in terms of psychology, adrenaline, etc. We can sit here all we want and type on the internet saying "once the threat is no longer there he should have walked away" but we obviously haven't been in such a dilemna. We'd have to BE that person to truly understand.
Even then, the man who was killed technically created all the events which transpired.
Edit - Wait, let's all think logically for a second. The intent of survival in some circumstances calls for you to KILL your attacker. Some people don't understand that this line blurs during such incidents.
