First of all...LEMME READ! I WANNA READ! PLZ LEMME READ!

Well, okay. This is definitely something I would discuss in the fanfic section. And I never noticed this little page. But I guess I should pitch in a little...
Firstly, cliche is good if its justified. And just because he's the supreme evil king doesn't mean he's cliched. He might be the supreme evil king that likes cats, does gardening, takes walks in the park and listens to David Bowie with a bunch of other homicidal bastards. Not your average evil king, eh?
But that was just a little something. Personally, even if we see evil kings every day, no-one gets too tired of them. And evil kings, like you've stated, are people you can relate to. Macbeth is an evil king; he slays little kids, murders the king, practices witchcraft, etc. But it is his characterization and our ability to relate with everything he does that really constructs the story. So there you have it; as long as you write well (and we know you do) you'll be fine!
And now...moving on to address other parts of your post...
REVEGNE! wait...REVENGE! YES! THE RIGHT SPELLING!
CONDOMS FOR ME! Hold on...sorry.
Well, you have revenge. Okay, so revenge by itself is cliched. Then spice it up! Have revenge, add a twist, make your characters squirm and you can laugh. Alternatively add sugar and make them hypo; that works too. Either way, revenge, even if it might be cliched is still a great subject to write about, and if you twist it around the right way, you've got your story.
Lastly...
You want to talk to CGM more than me. I am a dumbass at all this. She is the Hallelujah chorus. Or along those lines.

But...everyone knows you can actually write. Just be creative, think a little outside the box, twist perceptions and everything and you have a story. You can do it! Just put your mind to it! It's just basically how you decide to construct it that is the major thing you should focus upon.
And if CGM said something different, disregard what I say.
