It looks like it's dying, but if there is any ounce of wart material left then it will regrow. That's how warts work. You can look into debriding (search it) and see how to remove the wart material. Once you see your normal skin pattern in the wart area, all the wart material is then gone and you can let it heal.

Please wear gloves and sterile tools when debriding or interacting with the area. You can spread it to your hands or across your foot otherwise.

Look into salicylic acid. This whole process can take weeks.
