As others have already told you, xkill does not kill the process, it
just shuts down the connection between the client and the X server.

You miss something fundamental here: X is a _network_ protocol. That
you are root, administrator or whoever on your machine does not mean 
anything to the remote X server.

Yes it is. You should control access to your X server with xhost,
xauth, and options like -nolistentcp
Otherwise, worse things could happen like somebody grabing your
passwords.
