It’s not Ben as the whole gimmick about it is that Ben has lost what he is, what he was. So yes it’s the same character in the sense that Marvel tells us it is.
What you are describing sounds to me like Kaine when he killed Otto. Spider-man without ethics. But of course that isn’t enough in itself as a difference. We also had tweaked powers. Sort of how Ben had impact webbing and other tools as Scarlet. So expect Chasm(ugh that name) to have something to set him apart from Peter there.
Interesting is certainly not the word I would use. Good for you that you can feel like that after reading this. For me it’s just Marvel giving me more and more reasons to stop reading them.
On the difference with Peter: Kaine, spidercide, Venom have all dealt with plots like that. The difference Ben would have added they needed to remove to actually get him in that place. For me it’s just so numbingly moronic.
