I don’t understand this about Jiang Cheng

I get he’s a controversial character in this fandom and some people love him while others hate him. To me, he’s a very realistic character. I think we all know someone like him in real life or someone who could turn out to be him, even ourselves if we had gone through what he did. We never know. That’s what I thought after watching CQL the first time.

However, the one thing I don’t understand is why Jiang Cheng still blames Wei Ying for the Wen’s invasion of Lotus Pier even after 13/16 years. You would think after so many years and after becoming a sect leader, he would be able to look at the big picture and figure out that the Wen were coming for them anyways.

Ignoring all the other issues about why he hates Wei Ying, this one doesn’t make sense to me. It didn’t make sense to me when it happened and he blamed Wei Ying. And it doesn’t make sense to me that he still thinks that even after so many years. It’s like there was no reflection, no growth at all.

And I’m not even gonna touch the golden core issue because that’s a whole other thing I have an issue with, while I understand his reaction to finding out about it.
