Who really is the most deserving of the good place?
Among the 4 leads?
I'd argue Eleanor, actually. She's made the biggest turnaround of them all, and it now shouldn't just be based on time on Earth. She literally showed she was willing to sacrifice herself for others several times throughout the season.
I could argue Jason is the worst. I mean, he legit doesn't seem to care whose life he ruins. But then again, is his stupidity enough of an excuse to justify it.
Tahani seems the most deserving on paper, but is the most selfish in person. She's snarky, and does seem to have the motive of attention behind all her motives.
Chidi would be the most deserving, aside from him actually "killing" Janet. Even if he did it to stop someone else from doing it, it's hardly a heroic act
So, going strictly by the guidelines of the bad place itself, and not life before, I would rank it this way:
1. Eleanor- she's the only one of the 4 central characters that changed for the better. The others have either gotten worse, or stayed bad.
2. Jason- I believe his stupidity renders him oblivious to those he hurts. I don't think he means ill will. I believe intent is everything. And it's obvious he feels love.
3. Tahani- opposite of Jason. Everything she does on the surface is kindhearted, but her motive for everything is never for pure pleasure of others. It's for her own self gain.
4. Chidi- probably the most good natured, but the fact that he actually committed murder in a sense, I can't logically put him any higher.
So, interesting turn of events. The two who were deemed the most bad, I actually think are the most deserving of the good place.
