Verified step by step guidance

1. Step 1: Understand the nature of psychological profiling and the diversity among serial killers. Recognize that psychological profiles are generalizations based on observed patterns, but individual cases can vary widely.
2. Step 2: Analyze each statement critically by considering empirical research and psychological findings about serial killers. For example, not all serial killers have experienced childhood trauma, although it is common in many cases.
