Will Shiva be an Evil Primal?

[Exodus-E]

(...)

Primals aren't evil. They're forces of nature.

Ifrit - aspect of fire. Fire is violent and unpredictable. It cares not for friend or foe, it simply burns.
Garuda - aspect of wind. Garuda is no more evil than a tornado or a hurricane.

I agree with your post/list, save for these particular two.

Ifrit: He is violent, yes; but what he's really after is complete domination/worshipers.
You could argue that it's similar to fire in that all it does is expand and consume everything it touches (akin to "tempering" or "dominating", as an analogy), but still...he's not exactly "good".

Garuda: She is outright sadistic and insane, not to mention power-hungry. She's probably the closest someone would call "evil" here.
