That was not the point of my reply. The functional similarity is that the use of none of these tools makes you "weak". That blood magic presents a special moral question is uncontested, but a different matter and unconnected to that.
First, logic does not provide truth, it is a path by which a truth is explained.
That you disagree with someone's logic does not mean you are correct.
Also, from my point of view you're missing the point. It's not blood magic that makes you weak, it's what leads all the mages we've seen so far in game to use blood magic that makes them weak.
- Jowan: "I thought it would make me a better mage."
- Dorian's father: Doesn't have the courage to love a son who shames him in the face of Tevinter.
- Avernus: supreme narcissism converted to powermongering
- Uldred: fear of the world converted to powermongering
- Orsino: fear of the world converted to paranoia and panic
- Merryl: supreme narcissism converted to savior-complex
- A bevvy of lesser characters: fear of templars, mundanes or whatever boorish excuse is popular this week.
I don't care about hypothetical do gooder blood mage cutters performing self-mutilating acts for the sake of the "greater good". I haven't seen any in the game yet.
For me - weakness of character is WHY morality is even a question to begin with.
There are, so far, no good purposes presented for blood magic:
- Phylacteries
- Violence (not unique to blood magic by any stretch of the imagination - but when it's one of your only purposes...)
- Mind Control
Again, hypotheticals are not the best basis to make an argument on. I'm loathe to say it - but I'll "believe it when I see it" (I tend to think only the dullest people believe only the things they can see). I hear people talking about what a blood mage "could" do... yet, I see no in game representations of any of them doing it. Forumites claiming that's just some weird moralizing by the creators have no foundation to make that argument.
Lastly, I'm not making arguments about why anyone else should see the way I do. Nor am I explaining why I see the way I do. Simply that this is how I see it. Take that for what you will. It's just opinion and how I would proceed on Thedas were I to be somehow transplanted there.
