Hell is a real place of eternal torment but was never intended for humans. Hell is where Satan and his followers (a third of the Angels) will spend eternity away from the presence of God.
God is Holy and cannot be in the presence of sin. He created the Earth as a perfect place free of sin and created man in His image (character qualities). He then gifted man with free will as to not make them robots. He wanted love but did not demand it. Satan used this opportunity to one by one spread lies and deceit to separate us further and further from the original plan God had for us.
Now, all of us sin as a result of the original sins of Adam & Eve, and the ongoing spreading of lies. Anyone who sins cannot be in the presence of God, and therefore only has one place they can go when they die: Hell. By not repenting of their sins and choosing the salvation of Christ, they are continuing in their sin and have therefore chosen to be a follower of Satan.
Hell was created for Satan and his followers. In other words – God does not send anyone to Hell.
