If you know something bad will happen to those you love and have the power to stop it but don't then you don't love.
Innocent is children dying of starvation etc
If a parent warns his child of the harm that would come to them if they do something, and then they do it despite his ability to stop them from doing so, is that unloving?
At what point do you believe a human ceases to be entirely innocent?
This is very important, because the crux of your argument is about the definition of love and human responsibility. The other two parts (God mustn't be all-powerful/all-knowing) revolve around the idea that bad things happen and if God is loving he would've stopped those things from happening, therefore he mustn't have the power to stop them or the knowledge that they would happen.
