When someone made an announcement like in the above to family, friends, neighbors, even strangers in our historic past; it was for your own good. In short; don't cross me, I might hurt somebody. Let me be until I can get out of this evil fix I'm in! 

Unfortunately, people are Angry/Mad about many things small, great and in between; without giving us warnings for the good of others and themselves. The element of surprise in gun violence and self-flicked wounds are used to take lives in large numbers.  

Nothing good ever comes out of Anger/Mad behavior:

A. So then my beloved... let every man be swift to hear, slow to speak, slow to wrath; for the wrath of man does not produce the righteousness of God (Jas 1:19-20.

B. "Be angry, and sin not." do not let the sun go down on wrath (Eph 4;26).

C. A soft answer turns away wrath, but a harsh word stirs up anger (Pro 15:1).

D. He who is slow to wrath has great understanding, but he who is impulsive exalts folly (Pro 14:29).

"Anger Management" is an absolute essential for God's children.  GOD is our Divine, Supreme Counselor who cannot fail!
