Radagon is a fun boss, but you're a complete goddamn psychopath if you think Elden Beast is enjoyable in any way, I don't care what anyone says, Elden Beast is easily the worst final boss in any soulsborne game, bar none.
How? The entire game was about you having to find the lord of cinders and all the bad things that happened after so many rekindling. What else could be the final boss but cinder itself?
Why? You've never played Dark Souls? You don't know what happened to chosen undead after first part? It's more than lore-wise, I bet every ds fan was theorising about Soul of Cinder being an actual reflecting of themselves from the first ds.
when Gwyn take over the soul its oddly fitting and sad because if your going to put out the fire its Gwyn's last effort to keep the one think he has left going
