But they didn't know it would blow up the tower, they were just told by Zanmaron that something bad could happen, but no details as to what, whereas Armadyl told Zamorak what ended up happening.
The problem was, despite their friendship, there were too many trust issues and shading dealings going on. The head Green Wizard stole from the Red Apprentice's idea, the head Red Wizard hid the details of the demonic aspects from the Blue Wizards, and the head Blue Wizard led her apprentice out when that was revealed.
Had it all be laid out up front, no secrets, it would likely have been debated, theorized, and after a few months, either some sort of reluctant agreement would have been made, the spell would have been done, and everyone would be fine, or they would have needed two new Wizards to help.
The Blue Order isn't blameless here, but it wouldn't have happened if the Red Order was honest from the start, and that wouldn't have even been an issue if the Green Order's head hadn't gotten jealous and stole the research from the Red Order Apprentice. Hell, even then, they were still going to do it unknowingly until the Gray Order Apprentice revealed it was all the Red Order's doing.
Every group had some impact on the events in the end.
The Blue Order's head even would have been fine with the Demonic influence if it wasn't all Red's end:
"Mei the Grey: It's safe, Perien. I studied the ritual - it uses demonic power but it's safe.
Perien the Blue: You knew? Demonic power is never safe! We have to stop!
Una*a the Blue: I'm sure the demonic influence is minor. The core of the ritual is still Wizard Azris's Green magic.
Mei the Grey: Green magic?
Kelavan the Red: Mei, it doesn't matter-
Mei the Grey: Of course it matters! I was there when Kelavan made his breakthrough. This is his work!
Una*a the Blue: Azris, is this true?
Azris the Green: It should have been mine! I've worked all my life on this problem and then some kid has the idea - it should have been mine!"
