I like your story. It takes a common theme of daemons and gods a gives a twist to the myths. Why couldn’t there be a daemon with a conscience. You present it well and it flows, but there are a couple of most likely typos;
“...never has a demon, no matter how strong, evil, twisted, or rich, has survived the ‘aid’ ...” and most likely should be, “...or rich, ever survived...”
“...careless person make the mistake...” should be “...made the mistake...”
”It could even be teenage punks grafatying some public monument or train car and accidentally painted my ...” should be either “...that accidentally painted my...” or “...accidentally painting my...”
“...whichever careless person make the mistake of...” should read “...person made the...”
The sentence, “The things I saw when I found her hurt and alone,” seems out of place in the paragraph it’s in. Maybe move it to the end where you talk about what he finds.
I’m not sure why you hyphenated wretch-ed and curs-ed, it’s distracting and made me wonder why not just use wretched and cursed.
There are glue words like “that” that can be removed to improve flow and save words. Also I think giving them both names will make them more prominent and pull readers in more closely.
Please take a look at the writing resources available, there are many and I found them helpful with my words. It’s a good story, I like your character, the daemon, he has a conscience. A good start for a larger story.
Thank you for sharing your words with us and keep on writing with a lot of reading and study of the craft thrown in. “Never give up, never give in,” when it comes to your writing.
