Answer: Technically Steve was never intended to die in Stranger Things. The Duffer brothers wrote a pilot script for a miniseries called Montauk that would eventually become Stranger Things. In that version of the story Steve is a more overtly villainous character and is killed by a monster. The Steve character was reworked once Stranger Things was created due to Joe Keery's more likeable approach to the character.
