Foi a decisão de Manwë através da vontade de Eru *
Manwë previu que fora deste mal "novo bem deveria vir".
É bastante claro a partir do Silmarillion publicado que Manwë foi o voto decisivo quando se tratou do novo julgamento de Melkor. No entanto, Manwë tinha mais conhecimento do que podemos perceber, e embora sua decisão possa parecer errada, foi a decisão certa para permitir o crescimento do bem no mundo, também estava de acordo com a Vontade de Eru Iluvatar, o Criador
Antecedentes
Quando Melkor foi acorrentado. Ele foi condenado a "três idades" (Sil, III) de prisão nos salões de Mandos antes de ser permitido um novo julgamento. Os Valar sendo seres puros foram forçados a manter sua palavra e, portanto, após o tempo ter sido considerado, Melkor foi mais uma vez trazido perante Manwë,
For it came to pass that Melkor, as the Valar had decreed, completed the term of his bondage, dwelling for three ages in the duress of Mandos, alone. At length, as Manwë had promised, he was brought again before the thrones of the Valar.
Then Manwë granted him pardon; but the Valar would not yet suffer him to depart beyond their sight and vigilance, and he was constrained to dwell within the gates of Valmar.
... therefore in a while he was given leave to go freely about the land, and it seemed to Manwë that the evil of Melkor was cured. For Manwë was free from evil and could not comprehend it, and he knew that in the beginning ... Melkor had been even as he...
The Silmarillion - Chapter VI, Of Fëanor and the Unchaining of Melkor
A partir do Silmarillion publicado, temos a idéia de que Manwë havia sido enganado mais uma vez pelas artimanhas de Melkor e que ele, por meio da mentira, encontrou sua liberdade e pôde mais uma vez realizar suas maquinações.
* No entanto, em Mitos Transformados, Texto VII (HoME X, Anel de Morgoth) em um ensaio intitulado Notas sobre motivos no Silmarillion , especificamente em parte (iii) , Tolkien nos dá uma visão dos motivos dos Valar durante o Desencadeamento de Melkor. Em Mitos Transformados , o Professor observa que devemos ser cautelosos ao encontrar falhas no julgamento de Manwë.
But, if we dare to attempt to enter the mind of the Elder King, assigning motives and finding faults, there are things to remember before we deliver a judgement. Manwe was the spirit of greatest wisdom and prudence in Arda. He is represented as having had the greatest knowledge of the Music, as a whole, possessed by any one finite mind; and he alone of all persons or minds in that time is represented as having the power of direct recourse to and communication with Eru. He must have grasped with great clarity what even we may perceive dimly: that it was the essential mode of the process of 'history' in Arda that evil should constantly arise, and that out of it new good should constantly come. One especial aspect of this is the strange way in which the evils of the Marrer, or his inheritors, are turned into weapons against evil.
Como Tolkien afirma no ensaio, Manwë tinha mais conhecimento do que nós como leitor e estava ciente, através de sua sabedoria ou comunicação com Eru, que a liberação de Melkor era uma parte necessária do "processo de 'história' em Arda ". Esta ideia é repetida da mesma maneira no Ósanwe-kenta (deixado no fundo porque é incrivelmente longo). No Ósawne-kenta, Tolkien discutiu a percepção do espectador sobre a loucura de Manwë em suas decisões e a facilidade com que Melkor enganou os outros. No entanto, o professor novamente sugeriu que Manwë não poderia ter forçado Melkor a falar a verdade, nem os outros Valar (por telepatia), pois isso usaria o mal, enganariam o mal, coisa que os Valar não poderiam fazer. Manwë estava aberto aos pensamentos de Eru e realizou sua vontade, isso é percebido como maior que a sabedoria. As ações de Manwë garantiram que o plano de Eru se desdobre. Em um vão semelhante, foi apenas pela palavra de Eru que Manwë finalmente decapitou Melkor e enviou seu espírito para vagar pelo vazio.
If we speak last of the "folly" of Manwe and the weakness and unwariness of the Valar, let us beware how we judge. In the histories, indeed, we may be amazed and grieved to read how (seemingly) Melkor deceived and cozened others, and how even Manwe appears at times almost a simpleton compared with him: as if a kind but unwise father were treating a wayward child who would assuredly in time perceive the error of his ways. Whereas we, looking on and knowing the outcome, see now that Melkor knew well the error of his ways, but was fixed in them by hate and pride beyond return. He could read the mind of Manwe, for the door was open; but his own mind was false and even if the door seemed open, there were doors of iron within closed for ever.
How otherwise would you have it? Should Manwe and the Valar meet secrecy with subterfuge, treachery with falsehood, lies with more lies? If Melkor would usurp their rights, should they deny his? Can hate overcome hate? Nay, Manwe was wiser; or being ever open to Eru he did His will, which is more than wisdom. He was ever open because he had nothing to conceal, no thought that it was harmful for any to know, if they could comprehend it. Indeed Melkor knew his will without questioning it; and he knew that Manwe was bound by the commands and injunctions of Eru, and would do this or abstain from that in accordance with them, always, even knowing that Melkor would break them as it suited his purpose. Thus the merciless will ever count on mercy, and the liars make use of truth; for if mercy and truth are withheld from the cruel and the lying, they have ceased to be honoured.
Manwe could not by duress attempt to compel Melkor to reveal his thought and purposes, or (if he used words) to speak the truth. If he spoke and said: this is true, he must be believed until proved false; if he said: this I will do, as you bid, he must be allowed the opportunity to fulfill his promise.
The force and restraint that were used upon Melkor by the united power of all the Valar, were not used to extort confession (which was needless); nor to compel him to reveal his thought (which was unlawful, even if not vain). He was made captive as a punishment for his evil deeds, under the authority of the King. So we may say; but it were better said that he was deprived for a term, fixed by promise, of his power to act, so that he might halt and consider himself, and have thus the only chance that mercy could contrive of repentance and amendment. For the healing of Arda indeed, but for his own healing also. Melkor had the right to exist, and the right to act and use his powers. Manwe had the authority to rule and to order the world, so far as he could, for the well-being of the Eruhíni; but if Melkor would repent and return to the allegiance of Eru, he must be given his freedom again. He could not be enslaved, or denied his part. The office of the Elder King was to retain all his subjects in the allegiance of Eru, or to bring them back to it, and in that allegiance to leave them free.
Therefore not until the last, and not then except by the express command of Eru and by His power, was Melkor thrown utterly down and deprived for ever of all power to do or to undo.
