Nothing wrong with anger and rage.
They are human emotions.
As long as one does not hurt others or animals with it.
We all have these feelings from time to time.
If you want more insight into yourself you can search yourself
and try to find where it comes from.
That takes total honesty though even if you see things about yourself you do not like.
Embrace those parts as well since they tell you something about yourself and
that is very interesting.
After understanding you might get more insight into other peoples anger as well.

Nice poem = Upvote and a follow since I appreciate a human who asks himself questions :)
