Well plenty of the lesser demons use weapons. I think a lot of it is the fact that these prime and lesser evils just feel cooler without them! They are more dangerous and elemental when they're just shooting fire and slashing with giant claws. And can you even imagine fighting a Diablo that wields a sword? He would be diminished somehow by having a weapon. That tail is weapon enough...
Hey wait a second, why do weapons drop off them when they die, then? That eternal mystery! <_<
