OK then, what did he teach about it, and in the Greek language in which his teachings were written what were the words used, what did those words mean, and what did the word hell mean in older Bibles where the word appears. Because these are the things you need to ask yourself when you want to know what Jesus really taught.
The answers, are, in the Greek language the words used are Gehenna and Hades. They mean, respectively, a literal valley S and SW of ancient Jerusalem, and the unseen resting place of the dead where there is no consciousness, so you wouldn't be aware of any torture. The word hell, as used in the Old English in 1611 when the KJV was written, means covered or concealed, as a grave or tomb, or burial at sea. For example, Jonah called the belly of the fish he was trapped in hell, the Hebrew word sheol which is translated into the Koine Greek, as Hades (Jonah 2:1-2). The grave. No torture. No Satan and demons. No consciousness. Later the word became used to describe the pagan idea of being tormented with demons forever, and other variations or ideas of hell.
Something to consider. The wages of sin are what? Everybody answers "death." Not everlasting torment in a fiery demon filled place underground. Romans 6:7 says when you die, you're acquitted of all sin. No more punishment required. Ezekiel 18:4 says the soul that sins, and all souls sin, will die, and so can't be tortured forever in hell. Jesus didn't sin and yet he went to hell. (Acts Of The Apostles 2:31) God is, in effect, in hell. (Amos 9:2 / Psalms 139:8)
