No, I never said it is. I mean, from the point of view of Braev, who thinks ending Crystalism will save the world, it is. I said it twice already, I think, that I consider that reprehensible, but Braev's reasoning is also justified. The way he goes about it is all kinds of wrong, however. Ending the religion may not be the only way to "save" the world, but it is the best in the eyes of Braev, especially considering his personal vendetta. So once again, let me stress, I think Braev was wrong for killing innocent Crystalists, but he considered it the best course of action for saving the world.
And the game never really says Crystalists are wrong. It says the Orthodoxy is corrupt, true, but not awakening the Crystals still has great global consequences. So both sides are right to some degree. The problem is that neither wants to listen and see the bigger picture.
Also, Skyblade, what are you doing here if you haven't finished the game yet?

You'll ruin all the fun for yourself.
