I always just dismissed the Vita Chabers as part of the gameplay mechanic for most of the first game and never used them because it felt like cheating to me. Then they tried to shoehorn in an explaination about them being for Ryans private ressurrection uses, but made no effort to explain how the hell it worked or why the fuck he needs hundreds of the damn things everywhere.

And then somehow Delta can use them in the second game (I think, could Delta use Vita Chambers? Again I never used them so I can't quite remember) and made even less effort to explain that whole plot inconsistency.

Really the whole thing makes no sense and is best just ignored.

As for Splicers, I guess they just run around being insane and trying to track down ADAM, however they can. Admittedly there's probably varying levels of sanity, some people might be quite normal and well adjusted, certainly there are still a few normal people left in the city when Delta wakes up 10 years later, which begs the question why are they still stuck in that damn city of the dead?

And a more pressing question; if Splicers are all, by defination "spliced" and genetically modified, why do only a handful of them even have powers, when there are large amounts of plasmids out there with offensive capabilities that could aide them in aquiring yet more ADAM to feed their addiction?

Really the whole word of Rapture starts to make less sense the more you scrutinise it.
