Because a moment’s or even human lifetime’s suffering is effectively nothing when compared to eternity. Show me someone who wouldn’t trade a hundred years of suffering for an eternity of bliss and I’ll show you a silly goof.

And if that were a real scenario a mortal was faced with, yeah it'd be a good tradeoff; but we're talking about god, and he doesn't need to make those kinds of decisions.

So, just like my friend’s kiddo getting jabbed, yeah, sucks in the moment but no reasonable person would really call it horrific suffering given that, while unpleasant, it lasted under a day compared to her (hopefully) ~ 35,600 days on Earth. Saying because suffering exists on a human time scale when you’re talking about infinity is similarly silly.

The vaccine makes sense for us to do despite the pain because failing to do so leads to more pain - but all of our options regarding vaccines are all within a system that includes pathogens. If we had the option to just magic our immune systems to perfect without any suffering at all, you bet your ass that's what we'd do. But vaccines are the best we got. But god made the pathogens, and god gave us vulnerable immune systems to those pathogens. God had the power to create a universe without them, or without our susceptibility to them, but he chose not to, allowing us instead to suffer at his whim. Not all good.

You keep coming back to this “why can’t God make free will without evil? If he can’t, he’s not all powerful!” But it’s a basic definition problem. You’re effectively asking God to make 1 = 1 AND 1 = 2, which fine, could do but it eliminates the entire usefulness of 1 as a number.

Did you just skip over that whole spiel? I gave an example of free will without evil. So, now you're just just whipping up some strawman bullshit about '1=1 and 1=2' - I've already explained why that's not the case. You also skipped over why the ability to commit evil is always so pivotal to the concept of free will. Again, in the system that god made that is our universe, I'm not free to shoot lasers from my eyes or fart out unicorns: why are those any less of a requirement to having free will? Without those freedoms, we're just automatons, right?

Similarly, if the idea of free will is to find and reward good people and punish those who squander free will (by being jerks) free will probably necessitates the capacity for evil. (Otherwise, just stick with angels. Haven’t read the bible thoroughly but I’m pretty sure that’s basically the point of angels, perfect beings incapable of doing evil except for the one God made rebellious etc.)

Yeah you might want to read it a little more thoroughly before trying to defend it: scripture is pretty explicit about not giving a fuck about you living a sinful life, so long as you repent in the end. ...you're familiar with Jesus, right? That's kinda his whole story. Like, you could live absolutely stuffed to the brim with sin, defraud your way into a position of high office, use it almost excusively for greed and to do things like start wars to distract the world from your visits to some sketchy island to rape children... and then open your heart to Jesus on your death bed, and enjoy eternity in heaven with no consequences at all.

And going even further than that, according to scripture you can live an extremely moral life and still get thrown into hell if that moral behavior was for its own sake and not as a function that repentance. One of the stories is about the Pharisees, which is a big cautionary tale about walking the walk without actually believing in the message. Doesn't matter if you're doing good, if you're doing it for the wrong reasons, yer gonna burn!

...I grew up in a Christian household, church, sunday school, the whole 9. If your only exposure to it is through sermons and things like sunday school, you're not going to notice all the red flags, cuz they're not gonna talk about them. Start reading that shit on your own, and take the time to really understand what it's saying... it gets pretty fucked up. But again, don't take my word for it - read the fuckin thing.
