> If he were motivated only by the desire to do good would that change anything?

Sure. It would change my mind completely if I knew Bush genuinely was deceived by those around him and thought there were WMDs, rather than if I thought he knowingly lied to pursue an agenda for other reasons (e.g. boosting Haliburton's stock, settling a score, etc). I only bring that up because it's something I feel strongly about, yet I feel the motivation could change everything in my mind.
