Yes, eternal hell is a rather limited and inaccurate belief. I'm not in agreement with most black and white or absolute beliefs and statements.  For example, religion can be and is at times a cage of fear, but i find it's a mixed bag.  It has facilitated some constructive patterns, and some non constructive ones. 

  Re: the whole Creator issue you brought up, i do think it's possible that a Source Consciousness could be purely positive, creative/constructive, and loving in nature, but when it sparked off a part of itself and endowed it with "freewill", this could allow the condition of "un Sourceness" (or not Source like) to arise. 

  If that potential wasn't allowed, it wouldn't be true freewill.   The question is, did Source directly "create" that?   Maybe it was just a potential on part of the created that could and did arise?

   I intuit that this is exactly what happened.  Some consciousnesses that were created, in being given true freewill, they decided to create inharmonious patterns (in comparison and contrast with the original patterns) based on selfishness and separative tendencies, which more or less spontaneously arose after the experiment of the splitting and creation of individual consciousnesses, was enacted.   It was not the original "way" or pattern of The Source consciousness and awareness, but it was allowed to happen.

  Is this definitely true?  I don't know, and it's better to explore for yourself whether or not it is.   But, under more ideal conditions...

  Whilst feeling and attuning to a more PUL type love, and asking for guidance from the most spiritually expanded, aware, PUL attuned, etc. consciousnesses.  Going deep in meditation also helps for figuring out such ultimate, big pictures questions like this.

God does not send his creatures to an eternity of hell an suffering. It is the people themselves that plunge themselves into it by their terrible deeds in their lives. Hell is the dark spheres in the afterlife. The Masters of Light call it the unconscious worlds. Unconscious because those people don't know themselves.

It is in fact the unconditional love of God that ultimately gets them out of there. God demands that you return to him in full conscious. So in order to continue their evolution God will make it happen that they are reborn again and can continue their evolution. How that works is also beyond the understanding of the Masters of Light, but they see it happen. They can only acknowledge that and they bow their heads for that. They see how God takes care of everything.

But the next life of those people will not be easy. Their conscious has not changed. They have the experience of the long stay in darkness and that should prevent them from doing that again.
There is much more to say about that. I read most of that in 'A View into the Hereafter' by Jozef Rulof.

Anyway, God does not doom, there is only rebirth.

The three pillars on which God builds the Universe are: Motherhood, Fatherhood, Rebirth.

That same mechanism continues to be used for our evolution on the next planets still to come.
