The ori are bad... why exactly?

[Jeffala]

They're bad because they want to kill everyone who will not worship them.

"Those who reject the path to enlightenment must be destroyed."

This makes them evil. Requiring absolute, blind faith from your followers and killing anyone who dares to question your divinity makes you evil.

Well Christianity makes you suffer for all eternity if you don't follow their path, since I rank eternal suffering worse than simple destruction, would that make Christians evil?

In many US states (and countries) captial punishment is still present, those who do not follow the law are destroyed... Does that make the legal system evil?

Humans destroy things with much less significant causes, if anything, Ori are doing the universe a great service by destroying Earth... I mean, look at SG1, they've sigle handedly destroyed the Goa'uld, the replicators, the farmers (the ones with the bio bomb), countless Jaffas, and now the Ori (from certain points of view anyway)... SG1 probably caused and inflicted more destruction than Ori.
