I remember someone saying when that rumor came out, that he will stabbed by Harry with one of his daggers or something, than by Sandman with a sand sword, than Venom was suppose to bite Sandman, than Venom is suppose to kill Harry accidently when he saves Spiderman. Some said that Venom is suppose to be killed by Connors or Reilly(Adrian Lester) with a sonic blaster or something.
Bottomline is, no one knows who's going to die and how. It's all rumor and speculation. I don't understand why Sam would kill Venom or just Eddie, in the first place. That would be disrespecting Venom fans.... killing him after only ten minutes of screen time, at the end of a 140 minute movie, than give a whole movie to Carnage in SM4 with Lizard and possibly Kraven, like many on this forum have predicted. Give me a break. That does not make sense, even for a person who publically said he don't like Venom. IMHO.
