Imagine a father who has a child under his care. The father has plenty of food and absolutely no impediment or reason to not take care of his child. Regardless, he just lets the child die of starvation, while simply watching by while the child is withering away, crying and pleading for help. Any sane person would consider this father to be either mentally ill or extremely wicked. Any sane person would certainly agree that this person should be either locked away in a mental institution, or prosecuted for his crime. This is, after all, a perfect example of criminal negligence.
Or imagine another scenario: A father simply watches by while his child is being raped, tortured and beaten to death. The father has no impediment or reason to not interfere and try to help or, at the very least, call a police officer to help. The father sees every gruesome detail of this act, but does nothing to help, not even if his child is asking him directly to help. Again, any sane person would certainly agree that this father is either mentally ill or completely evil, and should be prosecuted appropriately.
A third scenario: A father locks his child in a torture cellar he himself built, and tortures that child for the rest of his life, and the reason he does this is because the child didn't love him enough. Any sane person would again agree that this father is a monster and belongs in a mental institution.
Now consider that according to Christian beliefs, God is doing this all the time: He simply watches people, his own creation, his own "children", starving to death, being raped, tortured and killed, being mutilated by disease and natural catastrophes... and does absolutely nothing to help, even though he's all-powerful and could most certainly do so. Not even if those victims are pleading for help directly from him.
What's worse, not only does God refuse to help those in need, according to Christian theology he will send them to hell to be tortured with indescribable torment for all eternity if they don't love him in the right way.
When you present these problems to Christians, all kinds of excuses will suddenly pop up to defend their god (even if they otherwise would agree with those scenarios I presented above.) It's actually quite ridiculous the lengths to which they are ready to go to defend their own theology.
By far the two most common excuses are "free will" and "Jesus died for us." Yet both of these are complete and absolute non-explanations and make absolutely no sense.
Imagine that the father in the scenarios above is on trial for his crime, and he presents the excuse that he "didn't want to interfere with the rapist's free will." Would any sane person consider that as a valid excuse and exonerate him from his negligence? Of course not. That would be one of the stupidest reasons ever given for not helping those in need.
Or imagine that he presented an excuse like: "But I already helped! I allowed my previous son to die to appease myself, so that my other children would be saved!" Again, any sane person would consider this to be an outright insane argument, and would certainly not absolve the father.
Yet Christians are constantly using these two excuses to absolve their god for his criminal negligence, and they do it with full conviction that these are valid and perfect explanations. And they are so obstinate about them that no matter how you try to point out how nonsensical the explanations are, they will keep repeating them over and over, as if that would somehow make everything alright.
And they have the audacity of claiming that God condemning people to hell for all eternity is the people's fault because it's their "choice." The "it's your choice" argument is one of the most obnoxious ones ever presented. It's basically a sadistic choice. It's exactly the same as if the father told his child "either you love me, or I will torture you in my cellar which I built for that exact purpose, your choice." Again, any sane person would agree that such a person would be a mentally ill monster that should be locked away. Except if he's God, apparently.
