How to evaluate the role of "Yu Ning" in "A City Without a Owner"? Why did he choose to commit suicide?

In the finale of "The City Without Owners", all the survivors on the desert island were found by the rescue team and fled to the outside world through the tunnel that had previously entered the desert island. However, Yu Ning received a phone call from his wife. When she saw the light in front of the tunnel leading to the outside world, she chose to commit suicide.

This part of the plot confuses many people, because Yu Ning has escaped from a desert island and can return to normal life. Why did he choose to commit suicide at this time?

First of all, Yu Ning betrayed his brother Luo Ran twice, wounded David Li Chen, killed Xie Ying and A Xin, and set fire to Jiang Xue. The reasons are different, but they can be roughly divided into two directions.

Injuring Chen Li, killing Xie Ying and A Xin, and setting fire to Jiang Xue are just to maintain his integrity and kindness, so that he can still enjoy the happy life brought by money after returning to normal society.

Even if he escapes from a desert island, he will be accused, so that Yu Ning's integrity and kindness in his wife's mind will completely collapse, and so will his small family that he has worked so hard to maintain.

On the contrary, Yu Ning chose to commit suicide, and what he did will naturally not be discovered by his good brother Luo Ran, so that his honest and kind people can stay in his wife's heart, and her wife can also use money and house with peace of mind.

The role of Yu Ning in "A City Without a Owner" is actually of great educational significance to the audience, because "when money and a house become meaningless, love and kindness are the greatest glory in life."

Everything Yu Ning did when he was alive was for love. He chose to face death alone for love, but his love was too selfish for his small family. But whether it is big love or small love, people can see the brilliance of human nature from another direction.
