Yeah that just makes no sense.
You either have aspects of your life that you consider good or you don't.
An example is in order, I believe:
I am in great (psychological) pain. I don't know how long it has been, but I think it's approaching six months, if it hasn't already been more than that. I write to express it, which results in it diminishing. Is the pain good? No. Is the writing good? Also no.
I don't think I have to explain why pain isn't good. As for the writing, it isn't good or bad. It's a tool to decrease the pain (evil).
Get it now?
Stop trying to over-analyse everything.
I read this as "Don't think about things once you see them the way that I do".
