Dr. Jackson and Morgan le Fay in “Unfinished Business”

[to Morgan Le Fay] I believe you. I do. I mean, I understand the fine line you have to walk. I realize the risk you're taking just showing yourself. But I'm sorry, I want more. You can pass that on to your friends as well. [to the room] Yeah, I know you're listening, [to Le Fay, in full passionate-speech mode] Because I am getting sick of hidden clues and cryptic messages. And Merlin was right that the Ori are a threat. But not only to us "lowers," not only to the billions of humans throughout this galaxy, but to your own existence. Because when this war is over, and every soul that's left alive is praying to the Ori, feeding their need to be worshipped, you know who they're gonna come for next. I won't pretend to know what that war will look like, or in what battlefield it will take place, but then, I won't be alive to see it.

If we interfere, we are no better than the Ori.

I understand that is at the very core of what you are, of what you believe, but I'm talking about survival here. If you really are trying to help, then help yourself.
