Does this not depend on where in the tree you are and what permissions
you have on . and ..?
how many more permissions will you have than root?
"rm" and "rmdir" take care to not delete "." or "..". "rm" also requires
the "-f" along with "-r" to delete non-empty directories. You don't
want to delete your current directory (".") and you sure don't want to
delete its parent (".."). Doing either orphans the shell you're in (it
has no current directory). Yes, you can delete them from another shell
and orphan the current one, but that's bad practice.
Unless you're ABSOLUTELY certain you are deleting what you want, you
should check the results of an "ls" and possibly use the "-i", "-I" or
"--interactive" flags.
