Assassination of Mickey O'Hare

"You won! You... you killed everyone! The bikers, the cartels, the Kitchen Irish, they're all gone!" "Yeah. Yeah, almost."

- Mickey O'Hare and Punisher

The Assassination of Mickey O'Hare was an attempt by the Punisher to kill the last surviving member of the Kitchen Irish.

Background
"Oh, shit, I'm the only one left?"

- Mickey O'Hare

After killing Ray Schoonover and helping Daredevil take down Nobu Yoshioka, Frank Castle visited his old house for the last time, retrieving a CD with the name "MICRO" written on it from behind a photo of him and his former platoon. Castle then proceeded to set the house on fire and leave New York with both the disk and the weapons he stole from Schoonover's arsenal.

Over the several months, Castle embarked on a campaign to kill the remaining members of the gangs involved in the death of his wife and children. Eventually, he eliminated both the Dogs of Hell, whose last two members were run over after a chase through Alabama, and the Mexican Cartel, whose last member was shot and killed by a sniper's rifle fired from across the Mexican border, before returning to New York City to kill Mickey O'Hare, who was the last member of the Kitchen Irish.

Assassination
"I get it. An eye for an eye and all that. I got a family of my own. [...] For God's sake, man, killing me is not gonna bring yours back! What does it change if I'm dead?" "Nothing."

- Mickey O'Hare and Punisher

Following O'Hare to in Queens, Castle found him in one of the men's restrooms, where he had locked himself in a stall and called an unknown individual from his cell phone. O'Hare, who was unaware of Castle's presence, told the individual that he had purchased a ticket to Dublin, Ireland and that he would soon be boarding.

At that moment, Castle burst into the stall and attached O'Hare, who tried to persuade the vigilante into thinking that he had killed everyone he needed to kill. Castle, however, was unmoved by the mobster's pleas, even when O'Hare mentioned that he himself had a family.

When two men entered the restroom, Castle began to strangle O'Hare with his tie. The moment the two men left, disgusted by what they perceived were two men engaging in intercourse, Castle, who by this time had strangled O'Hare to death, left the mobster's corpse in the stall and proceeded to leave the restroom.

Aftermath
"Look, you got half a life left to live, my friend. If you don't, you might as well be dead." "I am dead, Curtis. You didn't hear?" "Bullshit. You got a name, a passport. As I recall, Frank Castle's dead. Pete Castiglione, he's got a life."

- Curtis Hoyle and Frank Castle

Convinced that he had avenged his wife and children, Castle] destroyed his bulletproof vest and abandoned his former life, taking on the alias "Pete Castiglione".

After living as Pete Castiglione for six months, Castle was drawn back into his old life when he was forced to save a co-worker, which drew the attention of a figure from his past.
