It all depends on what you compare to. If you compare flying in africa to flying in europe, yes, it flying in africa is more dangerous. However, if you compare flying in africa to travel on road in africa, flying starts to look like the best way to keep alive.
If you need to travel in africa, you have two options. 1) fly 2) drive. Roads are in bad condition and people drive like maniacs in poorly maintained cars and trucks. Not to mention the chances of getting robbed on the road. Even (or especially) in DRC flying is significantly safer than driving!
I depressing example was in Kigali where a crj crashed to terminal. 1 pax and two bystanders died... not in the plane crash, but when the ambulance driving the injured from the airport to hospital crashed
If you want to stay safe... stay home!
If you want to travel in africa as safely as possible... fly!
