Hello Aiden Blackwood

This story is at the same time horrifying as it is strangely comforting. Offering people a safe place to be warm and experience company is a noble thing to do. The outcome, of course, is not noble. The first person narrator comes across as sympathetic, which is a typical emotional response to a main character. The character's intentions are good. Somewhere inside of that person, there is a desire to be of service, but that little spark that is seen in his victims would warrant tending to. Instead, it is snuffed out. For the sake of the story, this trajectory works well though.

The intro line A kind stranger offers comfort to the broken, but their help comes at a quiet, final cost. gives a little too much away. I think the word "final" is too strong for a teaser.

A guardian angel This is the title of the item. "Guardian" and "Angel" should be capitalized.

The Guardian Angel This is the title within the item. It's slightly different from the item title. It would make sense to choose one version I like "The Guardian Angel" almost a little better because the first person narrator is only one person and he seems to act alone.

Aside from the differences in the titles, I did not notice any spelling, grammar, or punctuation issues. Well written. I was absorbed in the plot right away.
