The Jets were leading 3-2 after two periods, but Carolina put on the pressure in the third, firing 19 shots at Ondrej Pavelec in the game's final 20 minutes to win it 4-3.
"This one will stick in there for a long time," Noel said. "To me, the bottom line with this game is that if we don't make the playoffs, we don't deserve to make the playoffs. That's the bottom line. We don't deserve it.
"You can go down the road record all you want, you can go down all the other areas you want, but if we don't make it, it's because we don't deserve to make it."
Winnipeg remains two back of the Washington Capitals for the eighth and final playoff spot in the Eastern Conference.
The Jets have 76 points this season, tied with the Buffalo Sabres. However, Winnipeg has a game in hand.
"There's a price to pay to win games and there's a price to pay to get in the playoffs. And it's not a sometimes thing," Noel said.
The goals were Miettinen's first and second of the season, and came in his 35th game.
"It's pretty irrelevant right now," Miettinen said of his new-found scoring touch.
He wasn't sure if the loss was due to his team's bad play or Carolina's strong effort.
"I don't know if it was because of them or because of us," Miettinen said. "I don't know if it was a lack of energy with too long of shifts or something, but the third period, I think, it was more about us going down than going up."
Winnipeg fans kept up their jeering chants of the visiting team's best player, this time yelling to Staal, "Jordan's Better!" in reference to his brother, who plays for Pittsburgh.
"That was fun," said Staal, who scored his 20th and 21st goal of the season. "I mean, Jordan's good, but I don't know if he's better. It was fun to hear that, and it was fun to score a few and get the apple on the game winner.
"I think they probably regret the chants they were making as the game went on, started to hesitate and we stuck with it and were rewarded with a big win."
Carolina was coming off a 5-2 win over Minnesota on Saturday afternoon.
"It's a gutsy effort, back-to-back games coming into a really tough building," Hurricanes coach Kirk Muller said. "This is the way our guys have been playing since Christmas. They go, give it everything they got. We had a short bench, had injuries there tonight and everything, but they've been finding a way to pick up points and I'm really proud of the group. Everybody's really stepped up."
The teams were tied at 1 after the first period, but Winnipeg went up 3-2 after the second on Miettinen's second goal of the game.
LaRose scored the winner with a wristshot after Carolina won the faceoff in its own end and rushed down the ice. He has a goal in each of his past three games.
Staal's second goal came on a breakaway at 10:24 of the third period and tied it at 3.
Jokinen sent Staal a long pass that he picked up just before the blue line. He finished the play with a shot that went over Pavelec's stick.
"The problem was, you couldn't stop the bleeding," Noel said. "That was the problem. That's sad. That's sad because we came so far. And to do this to each other and to disrespect each other like this was silly."
Carolina had a five-minute power play in the second period after Jets defenseman Zach Bogosian was tossed from the game for charging after he left his feet and knocked Andreas Nodi to the ice, who didn't return.
Bogosian had missed the previous five games with a lower-body injury.
The Jets killed off 3:43 of the penalty before the Hurricanes' Tuomo Ruutu shortened the advantage when he was sent to the box for interference.
Miettinen made it 3-2 with 1:06 left in the second on a quick passing play with Spencer Machacek, who was called up from St. John's of the American Hockey League earlier in the day.
After crossing the blue line, Miettinen sent a close pass to Machacek, who passed it back to him and Miettinen then fired a low shot by Ward.
