But that is the hope of many that evil can exist, triumph over the sovereign God...
This is a fantasy world.
Evil will end, on earth, when human life on earth becomes extinct via evolution, such as man destroying the environment that sustains him or via nuclear war or via natural disaster
Also, more importantly, a human being can end evil within their own mind (yet you are waiting for a deity to end evil, despite you yourself remaining evil)
If there was a sovereign deity then there would be no evil
Only a few human beings can end evil
However, the forces that create creation are themselves "evil"
I can simply look outside of my window & see the trees competing again each other for growth, & a certain tree flowering, and small birds coming to eat those tree blossoms, and a cat hiding under another tree ready to eat those small birds, despite the cat being well fed
Creation itself is driven by evil (but you cannot see that)
