I think your problem is you are taking parable stories gestated in the culture and context of dozens centuries ago and assuming they are meant to be believed and acted upon as literal.
Also, you're projecting an assumption about lack of free will as imposed by the omniscience of a creator being enforced dogma upon its members.
Neither is true.
I've never in 42 years of catholicism been mandated to take the bible as literal truth. Or to accept someone else's (the priest's) conclusions from it. I've always heard those in the church saying things like think about that, draw your own conclusions. etc. Maybe I've gone to remarkable and above average churchs, but I doubt it.
Also, free will, choice, is a core tenant of catholicism. You can *choose* good, aka god, or the opposite, which for literary narrative purposes we've called satan (its easier to write about polar opposites if you can anthropomorphize the concepts).
As I view the parable you allude to I draw one conclusion. God couldn't engrain a true free will into his universe, a nondeterministic nature, without two things: time, and a polar choice. So he needed the concept of evil to exist in order for sentience individuals to be truly able to exercise that choice. so yeah, he made it all. I don't see any self-contradicting end goals there at all.
This whole concept of a vengeful god is something that has fallen *way* out of vogue (again except for those fiery 2-brain-celled hick preachers out in B.F.E.), but its one that I see alot of non-catholics attach with glue to their impression of the church. I've never once heard a wrath and damnation sermon in my entire life, and I've been dragged to mass since the sixties.
Again, I no longer go all that much, maybe a couple times a year in a good year. I feel I "got it" and am set up ok. But every now and then I dip my toes back in for some nostaliga and all the comfort that can come from that. Every time I revisit a mass I come away with the feeling that "nope, they havent gone off the deep end."
Now ask me about Quran burning preachers in Florida....

BTW - free will, and time with it, may in fact be an illusion, or rather an artificial construct, to an all powerful being, but that doesnt mean they aren't real *for us*. In fact, imo, time is more interesting than free will, but they are interlinked. I think I posted some thoughts about this in here a few years back, I'll see if I can find the thread. Fun stuff to think on.
