Diction mattered a great deal to Christ. Gehanna (Hebrew: Valley of Hinnom; גיא בן הינום) was a location in Christ's time, that was likely associated with burning, destruction and loss - things that one might be expected to feel in the absence of the Creator.
Hades was where all dead went and remained until the day of judgment. Christ's reference to it as Paradise implies it isn't a place of suffering. Catholicism's Limbo implies it is a place of waiting.
The modern notion of Hell as a location dedicated to the eternal suffering of man, is quite different from either of those places.
Did God create this place?
One view[1][2] is that Hell isn't really a place, but rather a state of being, and the primary suffering of Hell is the separation from God[3]. God didn't create it, rather we ourselves created it by separating ourselves from God through sin.
