Other emotions can be put on hold and treated later. But anger is different. It doesn't build up slowly — it explodes at full force the moment it starts. And unlike other vices that just disturb your mind, anger takes complete control. It tortures you until you can't hold back anymore. You start wanting to destroy everything, not just what made you angry, but anything that gets in your way. Other vices move your mind around. Anger throws it off a cliff.
for other passions admit of having their case put off, and may be healed at a later time; but the eager and self-destructive violence of anger does not grow up by slow degrees, but reaches its full height as soon as it begins. Nor does it, like other vices, merely disturb men's minds, but it takes them away, and torments them till they are incapable of restraining themselves and eager for the common ruin of all men, nor does it rage merely against its object, but against every obstacle which it encounters on its way. The other vices move our minds; anger hurls them headlong.
