Correction: not "could" be removed, but "should" be removed.

END is not just a marker that indicates where a program ends. It is an executable instruction, and when it is executed, it performs EXACTLY the same operation as RTN.

There is never, ever, any reason to put a RTN right before an END. Never ever. And when you do, a kitten dies somewhere.
