Couldn't agree more, but there's not many that can write Kaine as well as Chris Yost does. Whilst I was happy to get the Scarlet Spiders three-parter, Kaine's 'voice' didn't sound quite right to me, based on what has gone before. It focused on Kaine just being a brutal, savage animal, whilst his portrayal in the Scarlet Spider was far more layered and less one-dimensional.
We haven't had the Epilogue issue of Spider-Verse yet, so we don't yet know if Kaine is truly dead or not. We don't know whether he still has access to the Other, or if it was just the Other, rather than the host, who is now 'dead'.
If Kaine's death sticks, and Miles Morales survives the Secret Wars event, I wouldn't be surprised if Miles becomes the Scarlet Spider of 616.
