The Ori

The Ori are PURE evil. I mean, PURE EVIL!! At least the Goa'uld are very cool, and evil...but the Ori...they're nothing BUT evil, as proved by last night's episode. They're forcing people to believe in them by making them sick, even killing them, then reviving them (or at least they did to a certain group of people)! The Goa'uld wouldn't-erm...can't...um...they're much better looking (except for a few, including the "he/she", Nirrti)! When a person becomes a prior, they get all ugly (okay, slightly cool looking, but basically ugly). And even I am afraid of these Ori! Or I would be if they were real. The Goa'uld...now they are better. They're liked...or at least they seem 10,000,000x more likeable then the Ori.

Here's a pretty good section from the Wikipedia about the Ori:

“They can be simply described as evil version of modern ascended Ancients. The Ancients (known to the Ori as "the Others") are well known for their fierce belief in free will. As such, they do not interfere on lower planes of existence at all. Contrarily, the Ori believe that not sharing the secrets of the universe to those on the lower planes of existence is an evil act and those who practice it must be eliminated.

The Ancients who came to our galaxy considered this to be a terrible abuse of power. Therefore, they decided to hide knowledge of the second evolution of humans in the Milky Way Galaxy from the Ori. It is their policy that humans may find enlightenment through their own means, in the spirit of free will.

There is evidence to suggest that the Ori and the Ancients are on the same level of evolutionary existence, and that they exist with the same powers. As such, both are relatively contained to their own Galaxies. Whilst the Ancients manifest themselves as glowing ribbons of pure light, the Ori manifest as ribbons of burning fire, searing the air as they move. Also the Ori have no compunctions against taking direct control of living beings, or completely changing them to behave as they desire...”
