A young man is walking with his wife in a park after dark. They are attacked and assaulted by a group of gang members. The man's wife is shot and killed at the scene, he is also shot and left for dead but survives.
The police are unable to determine who committed the crime and the case goes cold, even with the husband's identifying the man who killed his wife there isnt enough evidence to indict.
Months go by and the husband is inconsolable until one day. He sells his home and gives his possessions away, telling people he's going to move into a motor home. With the money from the selling of his home, he purchases weapons. Several guns with a sizable amount of ammunition and a sword.
He drives to the home that is the well-known hangout of the gang responsible. Backing up to the front door with his car, he opens both doors and begins playing music from the car stereo as loud as possible. He kicks down the front door and chaos ensues. In the firefight that follows, six gang members are killed outright including the gang member that killed the man's wife who is found shot executioner-style on his knees. The man is also among the dead, suffering multiple gunshot wounds and dying of exsanguination while still firing at other gang members in the house. He is found with a picture of his wife clutched in his hand.
A newly drawn-up will is found in the man's car leaving all of his remaining wealth and possessions to his remaining family.
What would you say this man did? And what would you call him?
