Hmmm...

I don't like the sound of my own anger. Why am I feeling it?

But my heart never, never agrees to injustice. Once you've exhausted all "nice" options, it's time for action. No second thinking at that time.

However - I should always know that the greatest challenge is to master one's own ego and never let that interfere with dispensing justice.

When it gets personal, that is when one must stop.

Do you remember the stories of the great sages, Prophecy? They never attack when personally angry. They only take action against general ill. That requires a great deal of mastery and a very selfless understanding of what's right and what's wrong.
