Actually yeah, Spidercide would've made more sense. He's morphological and stuff so maybe he can use his spider-goo to make other things not dead when he combines it with the Jackal's cloning technology. Maybe Spidercide's goop can be the thing that remakes a person while the cloning tells the goop what to make? Then when they degenerate and go nuts it makes sense cause a little bit of Spidercide is in every drop.
You could even bring back Ben and still make him a bad guy and use that awful costume from his re-launch and have it make sense. Of course he's nuts, he got remade by a bunch of Spidercide goop! That's why he look like Spidercide cause he's being influenced by a bit of Spidercide. Even the Jackal back in Sibling Rivalry was interested in making a new Spidercide. Yeah in hindsight why didn't they do that?
