Welp, the thread has already been necroed (ironic considering the subject matter) so might as well jump in
While the forsaken are portrayed differently in different zones/expacs/books we can paint a somewhat cohesive picture which is
1- normal forsaken civilians are relatively normal people who happen to be dead, kinda like the Adams family
2- the higher up the pecking order you go and specially in the military you find Scourge 2.0, exactly the monsters everyone insisted they were
Everyone is okay with slavery though, so long as forsaken arent the ones being stripped of their freedom/freewill
