Since nobody said it, I guess I will.

I would in fact use it at 0%.

It might seem blasphemous for someone on a site called "GUROchan" to do this, but not only am I on this site mainly for /f/ instead, but any /g/ stuff that I do like is largely based on the idea of either things being fantasy (people aren't actually being hurt) or things being voluntary (like intentionally amputating their own hand).

There's also the part where I try to follow the idea of "who am I to judge" with regards to others, and that includes my actions bringing death upon anyone that I wouldn't get along with.

Now if you want to get into semantics, one could argue that I am still judging others in the way of saying "I judge them to be worthy of living", but my view on that is that the living can become dead if they so chose to be, but the dead cannot become the living if they wish to. Therefore, leaving everyone alive preserves their free will to decide whether to live or die, but killing someone also takes away their free will and forces them to die.

...it probably helps that I likely have a more optimistic view of the future than most regulars of /g/, but again I'm largely here for /f/ more than anything.
