To not give place to belief in annihilation is not at all requiring a belief in a "monster deity". Belief that there is fair justice that God was providing deliverance from, to all, is very reasonable without need for giving place to belief in annihilation. "Destroy" could be anything, and it can be a process. One could suffer loss of everything in this world, and call out, 'I am destroyed', reasonably, without having been annihilated. I believe the dead are raised but not to life. Their fair justice can have them suffer the consequences while not having gained life, to the right degree. I do not have to conclude they are burning up then, because of imagery that might be necessary being shown in the Bible, which would be there for what cannot be depicted of what we could not understand in this world. All not having life in Christ will then have the consequence of always being sorry about that, but there would never be repentance which they would never be capable of then.
The Scripture teaches that when Christ returns the earth and everything in it will be destroyed. The earth will “pass away” (Matthew 24:35; 2 Peter 3:10), “to come to an end and so no longer be there; perish.” The earth will have “fled away” (Revelation 20:11), which is a term that means “to cease being visible, vanish, disappear.”
It's about life (exist for eternity) or death (not to exist for eternity), there isn't any confusion about it and we most certainly can understand it.

11Since
everything will be destroyed in this way, what kind of people ought you to be? You ought to conduct yourselves in holiness and godliness
12as you anticipate and hasten the coming of the day of God, when the

a new heaven and a new earth,
where righteousness dwells.
