Anger is a deep compulsion, an animal compulsion. It is a necessary feeling to establish perspectives in life but it will deprive you of happiness if you live from an angry position.
Anger is disabling to conscious processes and can make you react when you don't even know consciously that is what you are doing or in ways that you do not want to.
Of all the ways for you to leave the Declarator this is the most disturbing to the principles that the Declarator are founded in.
The principle of unconditional love as the purpose of life can dispel anger, so an opportunity to see or know the Declarators highest purpose as an evolutionary tool is offered here.
or........maybe it is.
