Jun Moxie was well-aware of his own psychology to be honest. He would've chosen to exterminate the entire Jun Family if he had been in Xiao Han's shoes! Why would he have cared about the City Lord's anger in these circumstances? Why would he have cared about Han Yanyao's acts of self-mutilation? [You've already decided to elope with another man. So, why would I care if you mutilated yourself? We'll talk after I'm done slaughtering them!]
[Anyway, it's not like the Lord of the City would make my entire family pay in blood for killing-off the Jun Family!]
However, one would find that Jun Wuyi was innocent if they were to stand on his side! [We didn't know anything about that woman. He met her by chance. How would he have known that this would bring such a brutish disaster? Is there no sense of justice in this world? How would he have known that his entire family would have to the price for his romance?]
