Honestly, I am very interested to see what happens with Saul's post-BB life. We have just seen tidbits so far, but you know they will give us plenty more before it all ends.
This kinda offers some interesting way to look back at his character.
In Breaking Bad Walter White was the protagonist, we followed his journey and while of course some deaths greatly mattered (For anyone living under a rock and still following this thread I'll just name the Ozymandias one), some others were random goons.
Saul was the comic relief, he was there from time to time to do his job, and then he got shipped away to Omaha with a new identity. Ok, Saul at least's gonna get out of there alive, bye bye, now let's focus on the final two episodes ever!
....and then you watch Better Call Saul, and that ending hits you hard. You watch good hearted Jimmy, that for all his mistakes could get his life straight if he'd believe more in his good side, and you know that it's all gonna be in vain and that he's going to hide away from everyone he ever knew to live a life under cover in Omaha. That's quite a terrible fate, even if he got away with his life.
This could be expanded to every other character I guess, for example that chubby dude in the white dress that got shot and killed early in the series, Jesse's friend.... see, I don't even remember his name but in that universe he had a family, friends, people who suffered greatly for his untimely and violent death.
This happens anyway in real life, we concentrate on our friends and family because we cannot grieve for any random kid that gets killed in a faraway country or for a celebrity that passes away, but if we'd get to see the good sides of everyone in the Breaking Bad universe, we'd get the full extent and enormity of all the pain Walter caused more or less indirectly with his actions.
