If gabriel can be killed with a Angel – Jäger der Finsternis blade why cant lucifer i know this is a old Frage

Lucifer probably could have been killed using an Angel – Jäger der Finsternis oder archangel blade, but no one thought of using one against him.

it could be that he was an Angel – Jäger der Finsternis but he have become a demon so he might be a dangel now and an Angel – Jäger der Finsternis blade won't kill him

He's pretty damn fast and strong. Gabriel was an archangel and still couldn't beat him, maybe Micheal could though. Having the blade doesn't mean Du can get a hit in. It wouldn't be as easy as with Zachariah.

Normal Angel – Jäger der Finsternis blades don't work on Archangels so they have special blades (Archangel Blades) that can kill other Engel but are the only thing that can kill each other. Lucifer cannot be killed with one of the normal Angel – Jäger der Finsternis blades since he is an Archangel and he used his Archangel blade to kill Gabriel. (don't worry I thought about this a lot when I first watched Supernatural)

Gabriel wasn't killed with an Angel – Jäger der Finsternis Blade he was killed with his own Archangel Blade which is Mehr powerful and rare to come Von since only Archangels possess them.

I think it's because certain fallen Engel can't be killed , like Lucifer.
