Is there something like an Independent in Religon?

I belive in God and stuff and heaven but i also belive that we are reincarnated before we go to heaven :/ i belive many things but some i dont really belive in, like hell for instance i belive that some parent made it up to scare children or maybe even God himself made it up so his people wouldn't go bad. So is there a thing were I'm an Idependant like in politics in some sort?? Or is there some kind of religon thing that im clified in?? I'm not sure where I stand. I was born a Catholic though and tried to be although the thing about reinarnation held me back. This is my theory::: Lets say we live a bad life right? so after that one we live another one and become a bit better and so on and once you are the best and kindest prson you can be.. God allows you to go to heaven so there really can't be a hell in this situation correct?? Is there a religon that belives in that or is it just me? Help please!! thanks xx
