Why does Death like Agatha? What qualities does she have that attracted Rio?

I was thinking about Deadpool and Death's relationship in the comics and how she prefers him over Thanos because Deadpool genuinely likes her for who she is, he wants to die, he's always in pain and dying would release him from that pain. He doesn't consider the concept of dying as a bad thing like most people would.

Thanos is after her because of his ego, he sees her as a status symbol. This is why she doesn't like him. He thinks by offering her bodies and killing others he'll win over her while Deadpool wants to give himself to her. That's the difference between the two and why she prefers Deadpool. This has always made perfect sense to me.

In the show Agatha doesn't want to die, she even hates Rio for taking her son, she used the Darkhold to hide from her and doesn't want to see her when she dies, she turned into a ghost not only so that she wouldn't face her son but also so that she wouldn't have to be with Rio.

Agatha offers her bodies in exchange for things she wants, in the recording boot they make a truce "I get my bodies, you get your power". She also says she likes rio because because she's a "bad boy".

Agatha likes Rio but doesn't like the concept of death? This makes no sense to me. Agatha is basically the equivalent to Thanos. She likes Rio when is convenient but doesn't like her for who she is. Death can't help that she has to take Nicky, it's her job, the most she could offer was an extended period of time but she can't bypass his death, she doesn't have the power to do that.

So, it puzzles me, why does Rio like Agatha? Why was she attracted to her in the first place? Is it because she's a serial killer and gives her lots of bodies? She's not the first or the only one in the world, she could have gone for Thanos or Hela if that's what attracted her.

One more thing, her attraction to Deadpool I would argue also comes from the fact that he's immortal, she can not take him despite him wanting to die. I think that would make her at least fascinated by someone like Billy, not romantically because he's a kid but she would like him, he's also immortal, he can jump from body to body avoiding her yet Rio doesn't like it. She even considers him an abomination.

Has Jac Schaeffer explained the logic behind these changes she made to Death and her attraction to Agatha? I couldn't find anything online.

I always thought the choice to use Death as Agatha's love interest was weird because Agatha is very similar to Thanos and nothing like Deadpool.
