Yes, Walkers can be killed, but only in a specific way.
According to the provided reference, the only way to kill a Walker (zombie) is by destroying the brain. While other methods, such as severing the head or spinal cord, can stop them, they do not result in death.
Methods for "Stopping" Walkers vs. Killing Them
Method | Effect | Kills the Walker? |
---|---|---|
Destroying the Brain | Results in death. | Yes |
Severing the Head | Stops the Walker; head remains alive. | No |
Severing the Spinal Cord | Stops the Walker. | No |
In summary, while Walkers can be incapacitated by severing their head or spinal cord, only destroying the brain will truly kill them.
