@Joe,

This is a really good point. I think its almost never wise to never "try" and change someone's mind about a view on philosophical matters. We, here in this corner of the internet, come to share and debate such issues, but by-and-large I'd say "no".
Many people I've known have - what I consider to be - some of the most inane, inept and fantastical notions. If, aside from forums like these, you try and change they're mind you're likely to get only one of two results: 1) You'll invoke their anger towards you. -or- 2) As you say, you'll be instrument to removing something that gives them comfort. Only when asked, or only in an open place for just such things should we question someone else's ideas.

It depends on the circumstances and your specific motivation for that occasion; but in a general sense I'd say "yes, that's selfish".
Joe wrote: Could it be looked at as a form of Altruism?
I suppose so, but I think we often times "fool ourselves" into this; that what is actually ego (and a need for validation) is some kind of charity - as if "I'm gonna do this guy a favor". Once again, it all depends on the context.
Thank you - nice question.
