An infinite punishment for a finite transgression is stupid. Advocating hell as a just punishment is to advocate torture which we consider unusual and cruel punishment. Combined, it's extremely strange to see an Omnibenevolent being to make such a place and send people there for all eternity (without even getting into the problem of Evil and free will).
I like the concept of karma and rebirth more than the concept of a hell and paradise. I mean, why would you let someone impure into a place of pure good (somebody will probably give me some weird explanation)? What if there's a "line" or center? If one person was slight above that center (+1) and another slightly below (-1) it doesn't make sense, for 2 people with not big of a difference, to go into extremely different places. I don't know much of the concept of Purgatory, but at least that sounds better than instant paradise/damnation for eternity.
Anyway, at least Karma, you cannot become one with the Universal energy (I don't know much about the Indian religions... or religions in general, lol) until you're free from Karma. So even if you do only one thing bad, you cannot just repent it away. It stays with you for all eternity, and the best you can do is try to be the best person in order to be reborn as a better person with a better chance of not gaining karma in the next life. Baisicly I like the concept of RESPONSIBILITY in Indian religions, whereas you have the infamous "Chick Tracts" where you'll see awful criminals get off scott free with a last minute prayer, while a good and kind Jewish couple will go to hell.
