You're assuming that the creation of suffering is evil when God does it - however it could be that if heaven exists as a place in the future where everyone's all good with what happened...
...then it might not be evil when God does it, it might only be evil when humans do it (because we're not capable of doing it in a way that's consciously creating heaven (where everyones okay with what happened) as a result... We can't arrange souls like God can. We can't live or operate outside of, or beyond time like God can.
...also, not that anyone asked, but personally - I'm an atheist. I'm just seeing how far these arguments can go with provisos like heaven, God as a time lord, and souls/at-birth soul agreements.
Oh, also God can patch up or fix up, or factor in suffering humans create, because being able to predict that something is going to happen isn't the same as causing it. Eg. I know the sun is going to rise each day up until an expected sun-death... Even if humanity creates the ability to make the sun rise, it doesn't mean the sun is currently controlled by us. Yet it's still predictable.
