Demon gods need ANNIHILATION's permission just as demon lords need the permission of the will of the Abyss to become demon kings.
ANNIHILATION is not selfish with power, considering that it has infinite energy. So it gave every world ender the power they wanted. Unfortunately, they couldn't handle it and lost their minds.
All of this was done instinctively. ANNIHILATION managed it even though it was unconscious. It is because its existence seeks to exert its will on the void even without its active control.
It created mad world enders when it was unconscious. These world enders just need a little nudge for them to go berserk. ANNIHILATION gave them that nudge now that it was awake to do so.
ANNIHILATION would have remained asleep if not for the fact that there was another entity in the void universe that was capable of taking away the control of chaos from it.
