I guess I kind of felt it was a wacky way to establish that, and I felt it wasn't necessary. The absence of it in the androids would be sufficient to highlight it. The aspect of Mercerism being unveiled as a fraud being the androids grand plan and it not mattering (because Mercer being a real deity was never the actual point anyway) was great at highlighting how the entire idea was just a bridge to far for the androids. I probably just have some bias here since I like the film's nuanced interpretation of the androids and having one of them show mercy at the last moment is a better twist to me.
