Doesn't this invalidate the whole purpose of this show? Are some evil characters just "beyond redemption" and can't be allowed to continue living? Instead of reformation or imprisonment, seems like MLP also teaches that obliterating your enemies' corpses can work just as well. Showing that gruesome painful deaths (R.I.P: The Mean 6, King Sombra, & Storm King) can Also be effective in resolving disputes and restoring peace & happiness to Equestria again.
