So lets start with what has Geeta to say about Anger or Krodh
“krodhad bhavati sammohah sammohat smrti-vibhramah
smrti-bhramsad buddhi-naso buddhi-nasat pranasyati”
The literal meaning of which is
From anger comes delusion; from delusion the loss of memory; the loss of memory causes destruction of discrimination; and from the destruction of discrimination he perishes.
