As I understand, Mictlan offered you (Kailasa) a truce deal. But you refused. I would not blame Mictlan when you would rather take over their land than fight Hinnom. Besides, Mictlan was on the defense for the last how many turns? 10? 12? Hinnom really has not began attacking you either. Sure one scout and one merc took over a undefended land each. And even 5 horrors could not break your siege on Mictlan capital. That's all it has done. But Hinnom will help to restore Mictlan territory and it will not keep a single province that used to belong to Mictlan.
