What ya be talking about lad? I blame magic on the deaths of Linny and all tothers in redcliffe.
That is rather narrow minded, blaming all of Redcliff's problems simply on magic. There were so many variables going on that removing any one or two of them would've prevented the tragedy from happening.
Yes, if Connor wasn't a mage, then it wouldn't have happened.
However, if Isolde wasn't so desperate to keep her son out of the Circle (because that would mean losing him forever AND their heir) he wouldn't have been in Redcliff for it to have happened.
If Jowan wasn't the apostate brought to her by Loghain (since she admits that the mage she hired to tutor Connor originally was hired by Loghain) then the events of Redcliff wouldn't have happened because Jowan was hired to poison Eamon, and if Eamon hadn't been poisoned then Connor wouldn't have been driven to such desperation that he would allow a desire demon (and he had no idea she was a demon at the time, which is proof that mages need training) to possess him and it never would've happened.
If Isolde hadn't been so determined to keep Eamon from knowing, since Eamon would've sent Connor to the Circle, it wouldn't have happened.
There are so many variables that magic simply cannot be the sole cause of Redcliff and nothing else.
