I don't really like Kiro as a person, but selling her out to Chow or to the Void would be dickbaggery for dickbaggery's sake.
Also she's one of Fen's favorites, so it's unlikely anything will happen to her unless you make it happen.
But i do awful things to characters I like all the time. Penny bimbofication, all the Urta bad-ends in Urtaquest, locking Doc Badger up for life. Usually I'm a bit of a softie about outright murder for anyone, though (except demons. They don't have souls.)
What the others are tactfully not mentioning is that Urta was/is widely regarded as Fenoxo's favorite waifu character in CoC. He wrote and coded a lot of content for her as a result, including a special quest where you played as her for a while.
What others aren't mentioning is that Urta was a huge character favorite in CoC, and not just because I liked writing her. She wrecked favorite character polls for ages and there were even plenty of positive comments about her in the 4chan threads, though this is back before the groupthink turned against her.
Also, I made sure you could horribly dump her and break her heart like two different ways, even though it utterly destroys her as a person.
Someone earlier mentioned her being a fursona - that is false, though she did spring from a concept I had for one originally.
As for my love of big-dicked, hyper-libidinous hermaphrodites... I'm not gonna apologize for that.
