You’re conflating this existence with all of eternity. Those are very different things.

Those are very different things, but I don't see how or where they were conflated. Nor how conflating them would even be problematic in this context: they'd both be within god's full scope of control, right?

Similarly, an all powerful, good God can be okay with someone suffering

So, not 'all good'.

self imposed constraints on power. If I build a system and choose to work within that system, that’s still me being all powerful.

And if that system you just built includes evil, again we're in not 'all good' territory.

I know that a half moment of unpleasantness means an eternity of bliss

According to self imposed rules that include evil

that’s a tradeoff a good and all powerful God may make.

A tradeoff? Why would god need to trade? If he wants something, he just makes it so -- unless he isn't all powerful. Or unless we're still in the self-imposed-rules that allow for evil, which again is claiming that god is evil.

(so I can reward free will, instead of just creating a bunch of automatons)

Yeah free will usually comes up in these conversations, but right out the gate that's an attack on god's power: does he not have the ability to grant free will without also allowing evil? And even if he can't, and ignoring that that claim is that he isn't all powerful: why is the ability to commit evil always a criteria for free will? We can't fly, shoot lasers out of our eyes, or fart out unicorns either, so with or without the ability to commit evil our freedom is still not absolute - does that make us a bunch of automatons?

Or rather, if the ability to commit evil was taken away from us, would we lose our free will? Let's look at your freedom of choice within the context of dinner. Half a second's thought, and I've got dozens of restaurant options, or grocery stores that allow me to cook up something that might fall outside of what the restaurants here offer: the number of options, while technically finite, are so mind-bogglingly huge that it might as well be infinite: so I'm gonna say my freedom of choice here is almost literally absolute.

One of those dinner options is to kidnap my neighbor's 4-year old, throw him in the oven, and cannibalize him. Why? Cuz god lets me, right? Sure it's illegal, but we don't care about legal authority, we care about god's. So if god snapped his fingers and changed our reality so that I'm no longer even capable of considering that, let alone committing it, evil is officially off the menu... but the billions of other possible combinations are still open, so I'd argue that my freedom of choice didn't actually change all that much. Does that make me an automaton?

...and what about the things that I already don't have the freedom to eat? Most of our reality isn't edible. And even if it was, I can only fit a few handfuls of it into my belly at a time - I can't have the moon for dinner, it won't fit. ...does that make me an automaton?

Point is our free will already exists within a system that has limits. Evil is one of many, many, many parts of that system, so even ignoring Epicurean Paradox, why is evil always a focal point of free will?
