Anger is often viewed as "bad"
I put these words "good" and "bad" in quotes, because the idea of good or bad is based on interpretation. We might think something is bad, but others might see it a different way. We might actually be wrong. I might view carrots as "bad," for example. But carrots are a healthy, nutritious food.

When we think of something as "bad," we hold a very low opinion of it and think of it as harmful.

Take pain, for example. Pain is bad, right? What would happen if you could not feel any pain whatever?

You would be in great danger. Pain warns us of a problem. Pain is unpleasant but it's not bad.

Anger has a "bad" reputation.
