Unfortunately, I agree with Ali.
If the Company believes a route is profitable and meets their safety criteria, they will operate there regardless of your concerns. If you tell them you don't want to go there, they will invite you politely to shut up or find another job - what else can they do? Well, actually, they could offer those that are less concerned for their physical safety or without a family to support a financial incentive to operate flights into unstable countries/war zones, but that is a Pandora's Box they cannot afford to open.
Some people have already voted with their feet over the current destinations. The Company was 'sorry to lose them' - but evidently not that sorry...
