Safe or not, it is UNIX ;-). Deleting a file is not actually
modifying the file, you are really modifying the directory the files
reside in. So, if you have write permissions to a directory, you may
delete any other file that is in there, as you observed. This can't
really be changed (this is the way things have behaved since the
beginning of the epoch).
