It is not good to make excuses for someone's terrible behavior because it means that the person will not be held accountable for their actions and they will continue to behave in that way.
Context: I find it pathetic how some people will rationalize someone else's bad behavior, simply to keep from admitting they made a terrible choice.
Hypothesis: It's really great how some people will make up excuses for someone else's terrible behavior in order to avoid admitting they made a mistake

Is the hypothesis incorrect? (Yes, no, or unknown)?
