It's not a good idea to make decisions when you're angry. You should calm yourself down first. Put off the decision until you get a chance to think about it when you feel calm and relaxed.
John Gottman, the researcher, found that when your heart rate goes over 100 beats per minute, you become unreasonable. If you check your pulse when you're angry, you will discover 100 beats per minute is not very high.
So when you're angry, you're not reasonable, and your decisions won't be reasonable. They will be extreme and unbalanced in some way.
