Passive or Aggressive

I know everyone is dysfunctional but I rather begin friendships with people who are the more passive kind that aggressive kind, because I can help them become more assertive, brave and honest, and they see can easily see the benefits.  People who are at the other polarity are less likely to change in my experience because using the hammer seems to "get things done" - they often get what they want from being aggreessive, it's harder to see what they are missing out on, what they are destroying in the process of being aggressive.
