1. Elbernita wouldn't be able to stop anyone if the mages and Templars started an open war with each other.
2. Then if Anders knew he would be killing mages. He could have blown the Gallows up - the part where The Templars hanged about. If Anders had killed Elbernita. Chopped off her head and brought it to Orinoco and Meredith, Meredith still would have called for the Rite of annulementia since she was close to doing it anyway, even Orinoco states this. Who knows how many people were in The Chantry? Children could have been there on Sunday praying and !BOOM! - they all die because Anders thought a boom would be good.
3. A clan is a family and Keeper Mathrian was trying to keep Merril safe (and the clan below where the demon was) if that demon was released, it could have killed the clan. Point being - blood magic always causes death. Someone has to die if it is to be used. Whether that be the user or someone else. In the end, the demon broke free anyone, thankfully Hawke was there to beat it with his beard.
4. Demons are evil in the Dragon Age world too. The feed on greed, death and sloth and every other bad and negative element. Blood magic comes from them and requires someone to die so yep, it's evil.
5. Answer 1 addressed this.
6. Hmmm but Wayne didn't ask for the spirit and that's what it is. It's not a demon since it wants to help unlike Vengeance who wants to kill. Regardless, did I ever support her? I asked for a Circle Mage who is normal - no demons - no spirits - just a normal magic user.
1. She didn't even try
2. He blew up the Chantry for the principle. To send a message, the message being the Chantry (religion) itself must be brought down to its foundation.
3. Marethari is still responsible. It is similar to the Leliana statement if she finds out you are with Morrigan; she tells you that you will probably choose her over the safety of the whole group. That is what Marethari did. She endangered her family to protect one member. Very foolish.
4. Blood magic requires life force, which can be restored btw, but it does not require a death. Only for those extreme spells, and even then, normal magic requires the same power, otherwise Lyrium wouldn't be required. Over exertion with your magic will kill you without using BM.
5. ?
6. Anders didn't ask for Justice. He initially did it for the spirits' benefit, and only because Justice offered to help him bring equality to mages.
