As the youngest of four siblings , I endured my share of torture . We ' ve all grown up to be a loving foursome , but my brother Kurt ( 5 years my senior ) was particulary evil ( in a teasing way ) when I was young . Let me share with you the story of an older brother and his childhood antics .

Question: Why did Kurt behave in an evil way when the speaker and their siblings were young ?
Answer: He had serious self esteem issues that he dealth with by asserting his power over his siblingsHe has always derived pleasure from causing others to suffer as much as possibleChildren tend to act mostly on instinct and have not when learned about consequencesHe is a bonafide psychopath and his early behavior is a clear reflection of this
