I killed someone

For the first time in my 30 hours, I killed someone. I was in a shed picking up a tourist map, and turned around to see someone pointing a rifle at me. In their hesitation, I spam crouched to dissuade them. They fired, missed, and I sprinted out of the shed, pulling my IJ-70, I shot at him. When he ran out of ammo he equipped a shovel, rushed me, and I dropped him. I felt even worse after realising it was the same person I met at the pier not long before. I don't like killing people.
