I'm not a Catholic, but I do not view this as arrogance. I view it as quite the opposite. If one believes that God is sovereign and that something violates His word, then it is arrogant to think that "well, he obviously didn't consider this circumstance - God must have made a mistake." I understand the concern about the current suffering of many and the potential spread of that suffering to others, but if one takes the eternal view, as the Pope apparently does, and views current events in that light, then it is a difference of priorities, not arrogance. Ask him his rationale and I suspect he would say that he would prefer that they suffer from HIV, but go to heaven, rather than use condoms and go to Hell. Again, I'm not a Catholic.
