"who haven't accepted atonement for their sins." What happened to Jesus dying for all our sins, past and future?
tl;dr If you don't believe then you're going to have to rely on what some call Karma to save you. Problem is, good intentions don't always yield good results.
"Karma to save you" - no, only You can "save" yourself. More like be reborn as a person, hopefully better or take yourself to hell (not really a place but more like state of mind)
How does the karmic system deal with bad things that happen due to good intentioned actions that you didn't foresee - or good things that happen even though you meant to do harm/evil?
Define bad and good in this context but lets say I am kind to you, you get all uppity and get hit by a truck because you thought you are special and deserve the way... Your karma.
It's very difficult to tell weather an occurrence or act is ultimately good or bad without being able to see far into the future. My question is, what force determines the outcome?
So it's only a good deed if it has a good outcome no matter what my original intention was? Like if I lend you $10 to get a sandwich and you get food poisoning it's on me?
why is it on you? Who sold me that crappy sandwich or who let the ingredients go bad. Maybe me. You are taking that stuff way to literally and way to linearly. Think 3D net + time
There's any number of examples. Giving to a charity that's actually engaging in human trafficking(cough* cough* UNESCO cough*. Give a fiver to a bum, he gets mugged by another bum.
point is, look around. Many people are in "hell" mental physical. Perverts for example are in hell. Disease, endless search for quick pleasure, more, still not enough, misery, suicide
