Blood on my hands

I wrote this following off a scene from the Novel/Movie/Tv-show "Tomorrow when the war began". Beginning from the section after Elle, Robin and Kevin return from exploring the show grounds, after the were spotted the 3 rushed to safety in a nearby suburb. They eventually reached a house for safety, but whilst hiding a solider came to inspect the house leading to nearly being spotted. The quick thinking Ellie came up with a way to save her and her friends, but by doing so it ended in a young soldiers death. Making that solider the first person Ellie has ever killed. This then leads to the beginning to my story where Ellie decides she needs to make things right whilst in a distraught mindset.
