Even the best-behaved children can be difficult and challenging at times. But oppositional defiant disorder (ODD) includes a frequent and ongoing pattern of anger, irritability, arguing and defiance toward parents and other authority figures. ODD also includes being spiteful and seeking revenge, a behavior called vindictiveness.
These emotional and behavioral issues cause serious problems with family life, social activities, school and work. But as a parent, you don’t have to try to manage a child with ODD alone. Your health care provider, a mental health professional and a child development expert can help.
These are adults with an adult version of a pathological vindictiveness that is generally seen in ‘problem children’.
Your uncle?
This is what you call Oppositional Defiance Disorder, plus also being in a death cult.
