If I, as a sysadmin give root rights to my user, and that user deletes my (real root) files, even from the Trash or anywhere else, then the next step includes such a level of violence that's not compatible with any kind of Code of Conduct.
If you give a user wheel/sudo/root privileges, then they will be able to delete the root user's files regardless of using this script. I will consider removing this line and thus the required superuser privileges in the next release.
