Venting is a healthy way of dealing with such intense reactions, especially if they are out of our control. Sometimes, the powers that be ordain things that cannot be shaped by our attempts to change them; when one half of a duel party refuses to alleviate the situation, the other half must depart. Providing yourself with a robust route of dispensing of your anger and spite will prove far better for the heart and mind in the long run than bottling it up or even allowing it to burst forth.
That's why the arts are so important: Music, painting, photography, writing all provide the most successful and healthy routes of attenuation. Hatred never helped anyone - Go write a poem!
