jesus talks of a rich man going to hell, he wanted to come back and warn his friends and relatives. Revelations talks of hell being reserved for satan and his angels and anyone else who follows in their ways. Satan wanted to be god, god had to defend himself, so he created hell for all his enemies. There is a war going on in the universe between god and satans kingdom. Dont join satans side through sin but repent, follow Jesus and live forever.
