The devil is among who or what? What not just finish that line rather than leaving it there awkwardly incomplete?

It is good advice if th devil is among us, to run away, lol.

The rhyme is a little forced at times: "away, pray, day, way" which I would have avoided doing. The poem does seem to read a lot better when you avoid rhyming, especially not more than one rhyme consecutively.

I thought that maybe the poem was about drugs, and drug pads, but then I read the description under the title and I can see it's the speakers disgust with the world and all its flaws. So, I suppose it's one who exposes all the realities of life to another. So, to me, it still reader more like a sinister place like a drug house or some other place of sin. -- but of course that could be the world too. I must admit, there are days I wouldn't wish to show anyone humanity, I guess it just depends on where you are at the time you want to make such an offer.

It is good advice to avoid anyone or thing that can bring harm to us, so these are sound words to someone the narrator cares about.
