If I had gone further and described the action a bit more, or made it more violent, it probably would have been a problem. But I think this worked out ok because it was more about making the reader despise the antagonist because he’s such a jerk. The kick helps solidify him as the monster he is.
Thanks for reading! If you like this story, check out my other one “The Longest Winter”. It’s far superior IMO. This story felt like too much of the same and I didn’t enjoy writing it as much.
