What do you mean by ''binary'' in context of trust, harm, friendship?
I don't necessarily completely trust or completely distrust someone. I might trust them in some situations but not others, or only up to a certain line.
Similarly, there are degrees of friendship, from casual business or social acquaintance up to someone I'd want with me for the best and worst that life has to offer.
And degrees of harm, from "gave me a shove when drunk" to "broke into my house with a firearm." Not to mention all the varieties of non-physical harm.
Shades of gray, not black and white.
