that's always a problem, Who is like DBZ and comic books.. with so many variant time-lines and canons, plus literally BILLIONS of extremely nasty villains.. some of which would easily be CMs in other media..

many Who villains are vastly destructive but what makes Valeyard different from most in Who anyway is if he can choose to be "good" or "evil" : as a great many beings in Who really can no longer choose (even Davros is unable to understand good, due to becoming so corrupted).. Master can never be a CM due to the fact he's too insane to know "good" or "evil" (especially modern Master / Missy).

I guess for Who lore at least heinous comes down to : "can the character tell he is doing wrong yet does it anyway?" if it is "yes" then they are (usually) a lot nastier than most others in the show (who tend to be stuck in a set mindset, delusion or so on..).
