Lawbreaker → It is formed from "law" (from Old English *lagu*, meaning a rule or regulation) and "breaker" (from the verb "break", meaning to fracture or violate). The word "lawbreaker" refers to someone who violates or fractures the rules or regulations established by law.
Think of someone who 'fractures' or 'violates' the 'rules' — that's why a lawbreaker is someone who breaks the law.
