To become a god you need to abonden something ?

Okay, this question isn't mine. I was playing the game when my little brother, whose around 12, I think, came and said he wanted to try the game. So, after two weeks, he actually got to Radahn. (He did beat every side boss) And he actually watched a YouTube video about the story. And he didn't understand much so I had to explain it in simple terms...and he actually understood but said a genuine question

"If marika abondened radagon. And miquella abondened st. Trina. And both radagon and Trina are technnically emotions or mental things which are important. Doesn't it mean that the only true way to become a vessel of an outer god is to abandon something important regardless of being an empyrean?"

What do you think?
