I rather prefer my antagonists grey themed, good and bad, as realistically I can do it. For example I have one character (only one) that I refer to as antagonist, we do see his soft sides and we understand why he does what he do, but his extreme actions just makes it so he has to go. I think this is what makes a grey antagonist, though the why part will determine whether he is good or badly written. Pure antagonistic characters can be good, but it is extremely difficult to portrait in the time we are in now. (So much have been done already, and the dark lord type is getting overused) What is your view on antagonist(s) and how to portray them & create them etc?
