If I may,
The passions are not good or bad in and of themselves, they are part of our nature. The use of the passions for good and not evil is what we are called to do. Remember that when the money changers angered Christ with their dealings in the Temple, he deliberately took the time to fashion cords with which to whip them and drive them away. Christ used his passions of righteous indignation and zeal for respect of God the Father to do some good, even though it hurt people. When a passion flares, a temptation rears up, or a thought comes to you, think "what good can I accomplish with this course of action?" and weigh the options. Your intellect will present options and your will move. As with any virtue or skill, start small and work up to great.
