Judge, Jury, and Executioner - Man made gods

Just going to write a few free short stories that deal here since these can't be made into full ones and so I can stay in practice while I take a break. I might publish a collection of them if I write enough like I did with Hopeless.

In a gunfight in the middle of the city, Damian's family gets killed in the crossfire. Though Damian gets shoot as well, he survives, but his sanity doesn't survive. The cops couldn't arrest the shooters since they got away and they aren't going after them as they have other crimes to deal with. Since Damian is a high ranking military officer, he gets the police to give him access to their database and he uses this to finds his family's killers. After secretly taking ammo and weapons from the police station, he goes out to kill. He ends up killing over twenty people in one day as they were associated with the people who killed his family. This gave him a special kind of satisfaction unlike any other. He wants to feel it again so he accesses the police database again and prints up a huge list of criminals and their known locations. With his full arsonal that he took from the military, he goes after each and every single criminal and kills them all including those associated with them. This feeling that he has is now insatiable so he steps up his targets. He takes a jet from an airfield and bombs a prison. After this, he knows that the military is onto him that he goes around killing people so he goes under the radar, but there are plenty of people left to kill who harm the innocent. There are governments who harm the people they govern and other countries they come in contact to so he goes after them next. He gets rid of one set of governors, but when he gets rid of another and comes back another leader has taken the previous' place. The people of the country are the ones to blame for the country's state which is clear to Damian. He sneaks into a military base and launches several nukes at the country which completely annihilates it. It also starts a nuclear war between several countries. Now there's another target who kills the innocent, him. So he takes a pistol. And shoots himself.
