Slaying Primals *Slight Spoilers*

[Enkidoh]

Primals however are pretty much stated as being evil, period. Even the moogle Primal (Good King Moggle Mog the XII) was shown to be a bloodthirsty monster who corrupted his moogle followers.Bascially, Primals corrupt not only those who summon them, but also anyone who happens to come into contact with them, ala, the tempering of members of the five races into mindless thralls of the beastmen (in 1.0 this was specifically mentioned as being the reason why the beast tribes, specifically, the Ixal and amalj'aa, turned aggressive, if not downright violent, almost apparently overnight - they started summoning Garuda and Ifrit respectively - due to being shown how to summon by the Ascians/Paragons.)

In fact, in 1.0 the negative influence summoning Primals had on the other beast tribes scared the sylphs so much they vowed not to summon their Primal, at least, until the Calamity caused a political schism in sylvan society, which by the time of ARR, those who stuck to the 'no summoning' policy were forced out of their homeland of Moonspore Grove, with those who did summon Ramuh turning noticeably purple as a result.

Not to mention the Primals' very existence actually direct threatens the planet itself - to materialize in the material realm they need to consume an enormous quantity of aether, and are effectively aetheric leeches - this was in fact the very reason Bahamut had been sealed away in Dalamud in the first place, he was such a danger to Hydaelyn's existence due to the amount of aether he consumes that the Allag Empire thought the best option was to sent him literally off world into outer space just to stop him from completely consuming Hydaelyn's aether.

Either way, despite the best of attentions, it is plainly obvious by what was stated in 1.0 and in ARR that Primals are evil period and are a danger to the very planet itself.
