It is a weapon powered by Omar in a bug form. The only weapons of sorrow are the OG thorn we see at the lumina quest and necrochasm from the raid. They had to be human weapons that were corrupted by the hive. I'm not to sure on bad juju. Toland intended it to be a weapon of sorrow powered by the sword logic. I'm also not sure on the crotas ends weapons as they belonged to guardians but were corrupted. Lumina is a weapon of hope. We redeemed the original thorn and freed it of hive corruption. Just like rezyl azzir would've wanted it, he used the handcannon known as rose. Then the hive corrupted it and turned it into thorn. And he became dredgen yor as a result. Similar to how anakin skywalker became darth vader from star wars. Hawkmoon is a weapon I'm not sure on. It was a gift from the traveler, just as ruinous effigy was a gift from the pyramid. So I'm not sure if it falls into a weapon of hope.
