why? they don't resolve conflicts that way - in fact, they would just watch them two resolve the conflict( Waver vs Archibald). Magi Association never interferes unless: 1) they want to get someone alive(who is really strong as a magus) to medically examine him(ie dissect him and put him into different jars) 2) they stop magus from revealing magic to general public.
Magi Association dosen't care by the 'route' taken by magus, it just want to see the finished products of researches.
Is that from the game? Because I don't remember them talking that much about the Magi Association in the anime or movie
You are here alone again
In your sweet insanity
All too calm, you hide yourself from reality
Do you call it solitude? Do you call it liberty?
When all the world turns away to leave you lonely
