The question of whether Bloodmagic is evil and Why the inquisitor can't be a Blood Mage are two different questions.

DaySeeker ,I wouldn't call my comment about the writers as ludicrous when seeing as how I'm referencing interview information.

They allowed us to be blood mages without all of those implicit, by your arguments, necessarily evil consequences.
Not everything is received as intended, though it is nice to see someone defending bioware rather than attacking
I have not read any of the novels, so I can't speak for that, unfortunately. I'll have to take your word on that, and I loathe spoilers, until I read it.
Imagine if it were explained as such:
Direct (and elegant??

lol)
Using blood magic. Sacrificing one's own blood leaves the caster in a weakened state, greatly increasing their vulnerability to demonic possession by spirits attracted to the empowered life blood entering the Fade.
Other mages turn to sacrifices, taking the lives of others to muster the power to cast their spells. In all cases, blood magic runs ever closer to catastrophe from unfettered power.
Wouldn't that have been nice and clear?
Addendum (potential codex entry pt2?)
'In the distant past, powerful blood rituals were cast through communal sacrifice. Mages gathered, and each making a small gift of her or his own blood. Such rituals may have unleashed some of the greatest of magics hinted at in long forgotten legends.'
Why this little addendum? It can be a nod to the ambiguity of magic. That's a safer means of performing blood magic, sure, but what rituals were used? Protection or destruction?
The writers have proven their ability to handle complex issues with the whole Templars vs Circle/Apostates, as one good example. I fondly remember the first major convo with Meredith. I (my character) was an apostate blood mage, (and all around nice guy

), yet Meredith spoke in a very reasonable and convincing manner. I could see and understand her position, despite the horrid conditions she advocated. What if Meredith were less harsh with her means and mages weren't pushed to desperation?
Great writing makes you think.
I think Merrill is a fascinating case. Unintended consequences. If one is ignorant of how to use a tool and causes harm, is the tool to blame or the ignorant?
"Blood Magic Poisons everything it touches." I haven't seen that happen.
What I have seen is Bloodmagic being dangerous due to Merrill's ignorance, or desperation: by many DA2 mages, like Orsino (a tragic and unpleasant example
I'll never forget that hand on Orsion's cheek! Beautiful! ), raw ambition: a number of powerful blood mages, ect.
I wouldn't argue against "bloodmagic is different", but simply stating that it
IS evil is so dogmatic that it takes away from more legitimate explanations that exist in the game, Which everyone can agree on, that examples actually do exist in some capacity.
Is everything evil also dangerous? (honestly, idk... it certainly isn't helpful/good...) Is everything dangerous evil? I would say no.
A quote I love "The greater the gift, the more tenuous the balance between benevolence and malevolence." -Tannarive Due (The Living Blood"
serious irony in that title lol
Back to Devs and reactivity:
Perception is an entirely legitimate concern. It's illogical to assume that a Blood Mage automatically uses mind control on any and every person in the same manner that an Assassin shouldn't be assumed to be willing to assassinate any who disagree with the Inquisition. In the scenes, the mind control wasn't undetectable, and it wasn't permanent. The victims were somewhat hazy. Additionally, the spell can be dispelled.
How many know those details? Not many, I'm sure.
to address my Assassin vs Blood Mage comment, people might be suspicious of an Assassin, but alive is alive. Mind control, like accusations of Communism,
thank you Chibi Elemental, cannot be proven one way or the other.
The leader of the Inquisition with the ability to control minds is a problematic issue for followers and allies. Blood Magic IS Evil isn't a strong argument. Blood Magic is Seen as evil is a better argument.
Feedback and suggestions should be helpful for the devs, afterall.
The question of: Is Bloodmagic evil isn't well set from my experience, but I'll take a look at Last Flight, as I'm a voracious reader (and clearly talkative

) .
I feel somewhat better about the lore issue and why Bloodmagic is being abandoned :'|. Also, seeing descriptions of the Necromancer specialization makes me happy to see no mention of raising corpses, which would be harder to swallow as morally superior to blood magic (not a universal concern, but I would likely not be alone in my surprise) as the Inquisitor isn't from Nevarra, and most other characters are not either. I look forward to seeing how that's implemented.
My only sorrow is over the lost mechanics of Mind Control/Confusion and Drain Life. Maybe they'll appear in game? *hopes desperately...*
