God created everything before Lucifer and when people die they wind up in Heaven or Hell.
There are countless videos on YouTube of people who were pronounced dead and saw both places.
Heaven is a place of peace
Hell is a pit of huge fires
When people wind up in Hell Satan cannot protect them because God is the one who administers the punishments.
People who stay loyal to Satan are meant to suffer and he cannot help them.
Walk away from him and go back to God and Jesus Christ! If people are afraid of Satan they will be protected.
He has no power over God and Jesus.
