Would it change the connotation of the sentence if I say "shouldn't" instead of "should" in this context?

In this case, since it is a question, "shouldn't" would be acceptable instead of "should". The question would still read the same. As a statement, it is best to use "should" with a positive and "shouldn't" with a negative. Ex: James, shouldn't we see what's on the menu before we sit down? I think we should. Ex: Why are you sitting on the bench, Timmy? Shouldn't you be on the field with the team?
