woah! who said anything about doomsday? what mage has wanted to bring about the end of the world? you seem determined to paint mages as cartoon villains.
and Im only half joking, take blood sacrifices as an example, your looking at it from the perspective that a slave is an equal person who doesn't deserve to murdered. But a tevinter would look at you oddly to a tevinter a slave is literally property they aren't equal so such opposition is incorrect its a non issue from their perspective.
a less macabre analogy is to look at the Chantry vs the Qun, there is no Inherent good or bad but to a qunari the chantry is superstitous nonsense and anyone that doesn't follow the Qun is a lessor being. To the chantry the Qun is Blasphemy, and those that follow it should be brought into the chantries light.
"you seem determined to paint mages as cartoon villains."
Well i don't have to honestly they did that themeselves 
Well to be honest i couldn't care about killing someone but what i value is sanity most mages don't have that and insanity combined with powers that can destroy world not to mention abomnations that is something i want get rid of... so i say to stupid evil or destructive characters goodbye.
And no comparing chantry to guys who kill childrens well for fun which says a lot about sanity isn't very on place...
Sadly not.
You can't judge every Mage in Thedas off of one group, especially one that has never been oppressed. I don't judge Templars as rapist pigs because Ser Alrik is a slime ball or as overzealous murderers because Meredith turned into a lunatic. There's good and bad in every group, on both levels. For you to assume one is worse than the other is ridiculous.
No? you did that before
you were judging group basing on minority there well few peoples i judge on majority so if for example majority of peoples in organization is corrupted we can say that organisation is corrupted when it is only minority you can't...
Not to mention that you call murderers guys who were killing corrupted and insane mages...
Yeah mages good sides ehhh aaa o i know they created new life called darkspawn wait bad example oh i know 1 anders was helping refugees for free oh and he then blew up church...
