For Heaven's sake

These days I am discovering a new religion and I wonder about my preconceived notion about most of the religions providing inner calm. I believe the moment you make too many rules in any religion its bound to get messy. As the society changes so does our ethos. The only immutable law that holds all the things perfectly is love. An unconditional love towards other creation of nature be it human or animal or environment. The moment we introduce conditions its become difficult to accept things as they are, so when I see these people have problem in spite of being a wonderful people is the flaw in the understanding of this basic premise. For ex there was this topic of this woman having so much respect for her one of her friend's father because he was a wonderful human but she regretted that he didn't convert to her choice of religion and apparently will go to hell. Does god really judges us of how we believe in him ? afterall doing a little bit of research it can be proven that most of the religions have undergone a tremendous metamorphosis since their initial conception and this process continues unabated. I say this because the moment we try to see people the way we see the world we are trying to impose a foriegn belief system on them. Our belief systems are all shaped by our past experiences, surroundings our exposure to different belief systems and our willingness to accept what we feel comfortable with.
Than there was this other person who feels that being a righteous person she doesn't want to feel judgmental to her fellow workers and that concern was shared by many other people in the group. The reason I thought is the more severe a religion becomes and demands more of a person't loyalty the person feels that by making those sacrifices he or she is getting closer to god but the problem is to assure the birth in heaven he gets distanced away from the very people in the first place they were trying to get closed with.
