What's wrong with believing in things?

It's not about cha;llenging someone on their beliefs and making them feel hopeless it's the way we explore through curiosity what basis the people have for their religion... hence the words: debate, open-minded, curiosity, inspiration, doubt, beliefs etc. How would people convert to being religious without someone talking to them about the beliefs and being informed? And how would someone change from something they were made to believe in if they are not challenged? Its not about religion per se it's the continuous fascination of what it entails tht causes debates. Lol without talking about it how can we discover what we ourselves believe in? I believe we are in heaven and hell and that if God and hell actually existed then everyone would go to hell. Because we all murder with every step we take. I got challenged in class and the girl said... the nuns at her school said that that commandment only applied to humans.
