If you do not have the choice to not love God then everyone would be robots. Sin, or in this case choosing the forbidden fruit would not have been a choice if it wasn't there.
You are arguing that evil must exist in order to be able to "choose" good. This is not the position of a
perfectly good creator.
Furthermore, there are all sorts of
choices (literally: an infinite number) that we "don't get to make" because God never creates them for us. For example, we can't fly (or otherwise travel) to Heaven while alive, so we don't have the
choice of whether or not to try to attack heaven. That's a good-vs-evil choice that we are simply not allowed to make. Does that make us all robots?
