It's actually hawke who's all out crazy rebel mage. He hates the chantry so much but he knew going around openly spouting his hate won't do anyone favor. So when he met anders, he felt like he hit the jackpot. He nurtured anders' delusion, subtly planting the idea of eliminating the middle way (grand cleric), romancing him to make him less suspicious of hawke's ideas etc. And after, using the event as a base to rouse mage rebellion everywhere. I'm okay with either anders dead or not in the end.
