Since I just had that scene right now - it is actually your character that suggest that Kagha should ... go. Zevlor says that he hopes for anotehr outcome, but when it comes to Kagha or the tieflings, then he is all for offing Kagha (paraphrasing here). I totally get tha tsentiment. We are talking about a woman, who put a childs life in harms way after all.
I must have misinterpreted the dialogue choice, then.😆
