Gruesomer is formed from "gruesome" (from Middle English *gruesom*, meaning causing horror or disgust) and the suffix "-er" (meaning one who or that which). The word "gruesomer" refers to something that causes more horror or disgust than something else.
Think of something that is 'more' ('-er') 'horrifying' ('gruesome') — that's why gruesomer means more gruesome.
