Fervency and Zeal are good things when they result from good things, but when they result from negative things, Fervency and Zeal make things worse.

Passion may be the child of Ignorance.

If passion is a sign of bigotry or prejudice, then Passion is actually a defense mechanism. It disguises a disconnect or a rationalization (dissonance). Passion may disguise this disconnect so well that the passionate person appears to be a person of character and strength. But in reality, this passion is a sign of a character flaw and a moral weaakness.

If on the other hand, passion is due to being fully aware of the advantages and disadvantages of both positions or choices, then it may allow the one who has taken a position to weather the criticisms of those who oppose.

The comfort zone is one of the main reasons for misdirected fervency. Passion in defense of the comfort zone is a sure sign that there is a weakness in the personal development of the defender.
