No, God lives in the hearts of all. Regardless of what any of them believe.God exists in people's beliefs.
People listen to what their religion tells them.
Not solely, but yes. Places without guns have fewer gun deaths. When cars got seat belts, there were fewer car deaths.
People listen to their conscience. Whatever argument you make is a reflection of you, not others. So do you listen to what some hierarchical authority tells you no matter what? Or do you listen to your conscience and follow that if there is a conflict between it and what you are being told? So try seeing people like you see yourself before you make such an argument.
A gun, a car and religion are effectively tools. They are neither good nor bad. They can be used for good or they can be used for bad. It's not the fault of the tool. And to see it any other way is to transfer control or power to an external source. Which is not a good look.
