Calm down, calm down! Your deadly sin is wrath!
We don't want to make you angry, but...you're guilty of Wrath. Your answers reveal that you have a weakness for throwing a wobbly a bit too often. (Perhaps you're suppressing some bitterness - if so, try to get to the bottom of it.) There's definitely more to life than yelling at people and devising different means to intimidate them. You may be able to release some of your pent-up anger by joining a gym. Or, go the other direction and buy some scented candles and give yoga a try. Next time you feel like exploding, fight to keep your temper under control and try to find a way to express yourself in a manner that won't offend others.
Why is wrath so bad? According to early religious scholars, wrath destroys kindness. They believed anger must be regulated, lest it pervert the growth and well being of the soul. Try to temper quick impatience with tolerance and compassion, especially since mediaeval Italian poet Dante Alighieri wrote that wrath, along with pride and envy, is one of the deadliest of the seven sins.
