@mommunism Right, sorry for the misunderstanding then. But you still put forward the notion that autism is an absolutely negative trait for romance, which I disagree with.
So because she killed people, she is objectively impossible to like? By that logic, any soldier would be forever doomed to a single life after the first kill.
How are you sure demons kill for fun? Was it ever made clear who made first move in the war? Maybe 
humans started the killing in the first place, and the demon mindset is a fight for survival.
Right, listening to a disembodied voice, whose intentions you know 
nothing about, is self-evident. And this somehow makes him a better person than Risu, who 
might have an 
actual reason for killing. 'This saves lives' is basically the same to an adult as 'shiny' to a kid. Someone could put 'this saves lives' on the launch button for all the nukes in the world, and the person who pressed it would be completely guilt-free, right.
It's clear you're not even considering other view-points than your own, so I have no interest in discussing further with you. This is my last reply, have a good day.
