But if you used nerve gas in self defence to fend of someone that was intent on taking your life(If that were somehow possible.)? There is no moral attached to any weapon.
then if i had a canister of nerve gas and a gun.. and the police raid my home.. i should use the nerve gas yes? umm.. intresting post.. but holds no water..
anyway.. each way has some assumtions.. since cystal heals its assumed to be good.. and dark way is spose to be tourture and things like that.. which is assumed to be evil.. red way would also be evil 
just becuase
Eh, I'd say red way is more chaotic and unpredictable then evil... Like a fire, which can either aid or hurt.

If I say "Dark _____", other then skinned, most people will assume it to be evil. In traditional fantasy, dark blades are usually evil and such. The dark way is obviously meant to be more evil leaning with the power to corrupt, weaken, steal life, etc. This doesn't mean that it can't be used with good intent, it's just that the spells themselves are probably more leaning towards what's traditionally associated with Necromancers/Dark Mages and the like in rpgs, which are often evil.
And Healers are usually thought of as good... Clerics, healers in most rpgs, get their power from good gods and have spells against undead. Of course, if they're using their healing power in bad ways, then they arn't necessarily good...

While we're on the subject of glyphs and wishes:
What I'd personally like to see is a number of spells that do base things and then add predictable effects: for instance, the base glyph of arrow, an effect glyph of flame=flaming arrow. They'd probably be in the way of the effect glyphs, but require some knowledge of the other ways to learn (e.g. 1-2 CW, 3-5 RW for that). And Flame would add flaming/flame/fire to the base glyph, for instance if there was a sword glyph that conjured up a sword to attack your enemy, add flame and it'd be a flaming sword--it would have the predictable effect of adding fire to the original thing... Summon glyph + fire? Fire elemental or the like. You get the idea. Or something like that: This would add an element of predictability to glyph combinations that would make sense while still offering new things: and it would give every way a HUGE base of spells. (I'm not saying that every glyph should have the ability to be both a base glyph and an effect glyph, or even that some glyphs should have either possibility--But the basic glyphs other then arrow should have that possibility). This would add a uniqueness to each way while adding a predictability that'll allow people to create spells based on what they want, if they know that something is a base glyph and they know that something else is an effect glyph.
Only issue with this is that it might add a sort of "sameness" to the various ways that the devs might dislike, understandably as well. I won't argue for or against it, it's just something I'd personally like to see, not something that's needed.

Back on the original subject: I think Coneitic is right about the current abilities of the various ways--CW is the only truely useful one in a fight, as you can get off an arrow and then start fighting, which can make that 5% difference between living and dying in a duel--as I know from a bit of dueling that I've done for practice with friends, and agree that they all need a bit more umph to make wizards more then just a sideshow or a support type. Perhaps a more powerful version of energy available without cheating? Healing a mere 10% at most seems kind of weak, although I am only 5 CW right now--meaning that it probably gets more powerful before CW maxes.

And another tidbit, this time about the dark way:
Also, something that I think would fit the dark way is having a number of ways to use other way's glyphs; Since the dark way is the most inventive in good and bad ways, I think this would characterize it quite well.
