Buddhism views greed, anger, and ignorance as the root of suffering that stifles our well-being. It is beneficial for us all to minimize these negative emotions regardless of faith.
Here is how the Buddhist monk Shunmyō Masuno describes them:
“When we are afflicted with greed, once we acquire whatever it is we desire, we are still left wanting more.
"Anger makes us enraged by the slightest things, and once it is provoked, we take it out on others.
"Ignorance is a state of foolishness: we are heedless of common sense or knowledge and lacking in education. As long as we allow ourselves to be governed by these three poisons, we will be unable to find peace.” — From Zen: The Art of Simple Living by Shunmyō Masuno (view my summary).
