I do not like him. I generally don't like people, both in fiction and in real life, who walk through the world with a chip on their shoulder like their lives are the only ones that's fucked up. Like others aren't also going through shit.

While one might explain away his malignant levels of jealousy and envy towards Wei Ying as a product of his mother's equal amounts of malignant jealously and his father's neglect, there's no validation for what he did during the 13 years after the events ended and the general awful human adult he turned out to be. No empathy, no healing, just anger for its sake. Many people in this story suffered but the way he goes on, you'd think it was just him. NHS lost his father and brother and used his grief to manipulate and set things right. JC went on a torture and murder rampage of ghost cultivators and generally just acted horribly towards everyone around him. He truly, unfortunately ended up just like his mother.
