Did I describe the following concept correctly?

In a discussion, my meditation leader was talking about people who cannot control their cravings and wants, who are easily subjected to actions based on their whims and wants of their anger. He associated these people with having akusala thoughts. He could not find the English word to describe the person, and so I gave him the word **impulsive** as a way to describe these people. Was this the right word to use, and is there a better word that I could have used?
