but we are now talking about 5e\
Are we? This thread doesn't have the 5E tag in front of it.
dude, how is live fire showing you wont abuse people... congrats on being able to kill things with your magic now please don't kill people with your magic...
The purpose of a live-fire exercise is to show that you know what you're doing; the Test doesn't have an alignment qualification to it. The point is to show that you're able to be a responsible practitioner of magic, which is a separate consideration from your moral standpoint (unless you conflate "responsible" with "Good").
no country I know of has you fire live rounds at a living being to prove you can shoot... you shoot targets.
I suspect you're overextending the metaphor here, since guns lack the breadth of effects that magic is capable of.
the rule books is what I remember saying it... but the wiki is what I can link I admit the main character does show it to be diffrent.
Things like that are why I prefer to go right to the books rather than wikis; as it is, I can't help but notice that the wiki doesn't have a citation for that particular passage about erasing memories before the Test.
peace where 1/3 of all people that can alter reality are known to be evil...
Where "peace" is the absence of open warfare, yes (though as I noted last time, you could also call that detente).
nobody is saying to start a war BUT you
That is the natural end-point of your stance about how Good wizards should morally object to Evil wizards to the point of opposing them in all things. If you have them belong to separate organizations, which are naturally at odds with each other, it's going to be war. Cold war, perhaps, but war nonetheless, and so will necessarily be more destructive than how things are under the Conclave.
this isn't "evil will always be there" it's "Well since evil is going to always be there I will work with and protect evil... even from other good people"
The problem with that idea is that it isn't true. As noted previously, White Robes can and do oppose Black Robes; they simply don't make this an organizational mandate. Respecting their right to exist is not, unto itself, in contravention with being good-aligned.
