No sir, I'll try to explain it. The Buddha has thought us as to how to live a righteous life. It is up to us to use logic and reason to see if it agrees with us, then practice it. Not adhere. If anything else , if there is any other way to live life it is solely our decision. Buddha never said we go to hell if we lose faith in what he thought. By the way Buddha was human. Just like you and me.
"No one saves us but ourselves. No one can and no one may. We ourselves must walk the path" - Gautama Buddha
