The widow of the thug who executed a Jersey City cop over the weekend said Monday that her husband should have killed even more officers — as her neighbors set up a sickening memorial to her fame-seeking spouse.

“He should’ve taken more [officers] with him,” Angelique Campbell said of husband Lawrence, who killed rookie Officer Melvin Santiago in an ambush early Sunday, before being killed by police.

“Sorry for the officer’s family. That’s, you know, whatever. But, at the end of the day, [Lawrence] got a family, too. All they care about is the officer,” Campbell added in an interview with News 12 New Jersey.

Jersey City Mayor Steve Fulop called Angelique Campbell’s remarks “maniacal and crazy.”

“At first, I was angry, and the more I thought about it, I just feel more sad for her, that she lives her life in that sort of mental state,” he told The Post on Monday.

Campbell made her inflammatory statements at an impromptu local memorial to her husband, who was fatally shot after he killed Santiago, 23, outside a 24-hour Walgreens store.

Lawrence Campbell, 27 — who had been wanted for another murder last week — blew away Santiago after boasting to a witness, “Watch the TV news later, I’m going to be famous,’’ officials said.

Neighbors set up a sidewalk shrine to the fiend, piling empty booze bottles and candles directly under a “no gathering” sign.

The site also featured two T-shirts bearing handwritten messages including, “REAL N—-Z DONT DIE,” “Forever a ‘G’ ” and “SEE U ON THE OTHER SIDE.”

The display infuriated Santiago’s stepfather, Alex McBride.

“They have T-shirts up for him; they have balloons, like they’re glorying him in the neighborhood,” he railed.

“He was a baby. My baby,” said the stepdad, who raised the slain hero from age 9.

Just recently, he’d asked the young cop if he feared dying on the street. “Well,” the officer replied, “at least if something happened to me, being a cop, at least I go for a good cause.”

“What kind of society do we live in where memorializing a violent murderer is acceptable?” said police-union leaders Officer Carmine Disbrow and Sgt. Robert Kearns in a joint statement,

Campbell later tried to take back some of her words, saying, “I do apologize. I was very angry.”

But she also kept up her criticism of the cops, complaining, “They called an ambulance for the officer — why didn’t they call an ambulance for Lawrence?”
