why people get angry?

Getting angry is natural. Everyone has his own thresh hold level after which he turns himself to a wild beast that cannot be controlled by reasons and logic alone. On many occasions I have experienced people in this state of mind what I found common among all of them were they don’t have the reason to prove their point or opportunities to express their abilities or when they found themselves helpless in a certain scenario thus turning angry followed by getting violent which can be both physical and verbal. Last but not the least personality disorders, deprivation or lack of proper attention in early life results in formation of unstable personality that all emotionally unstable and thus prone to socially unacceptable behaviors.
