Brainstorming

Aggression -> Abuse-> Family abuse -> neglecting  parenting -> ADHD -> problems in society -> problems in school -> family problems -> Cruelty -> Psychological problems -> Aggressive behaviour -> Suffering people -> "why?" -> "the problem is me" -> "help" -> "support" -> "freedom" -> "distracting" -> "abstracting" -> "feeling of sympathy" -> "understanding" -> "get rid of feeling guilt"...

Ideas:
1) Family abuse, neglecting parenting cause wide range of social and psychological problems that can lead to aggressive behaviour.
2) People think that aggression is caused by their actions or words.
3) To free from feeling guilt it is necessary to "forgive" an abuser and prescind from the situation.
