The Emperor talks too much.
Luke was clearly never trained in repartee.┬á As soon as it was clear Emps was going to monologue, he should have just fired back.
EMPEROR:┬á monologues about the Dark Side.
LUKE:┬á Forcedamnit old man, are you fucking trying to talk me to death? Shut up already.
EMPEROR: monologues louder.
LUKE: Seriously, dude, the first "Death Star" (finger quotes) got splattered, just like those drone control ships from the Trade Federation.┬á You weren't even original, and wasted a shit ton of money.┬á Is your dick as shriveled as the rest of you?
EMPEROR: monologues about "insignificant rebellion."
LUKE: Yeah?┬á So why did you bring an entire fleet AND a "Death Star" (more finger quotes)?┬á It's pretty clear you're scared. And why a second "Death Star"?┬á The first was Viagra Star and this is Cialis Star?┬á What's next?┬á┬á Some sort of planetoid that drains suns or something? How original.
EMPEROR: Angrily monologues about the power of the Dark Side.
Luke:┬á Are you still blathering?┬á If it's so damned powerful, why the shriveled face, shriveled dick, reliance on mundane weapons and unoriginal thinking? You don't even have a harem?┬á It's pretty clear why it's "Dark." It's the opposite of "Bright." 'Look at me! I rule the galaxy!┬á I have to send entire fleets around to get the shit kicked out of them by wookies, retired Jedi, half-witted smugglers and gamblers and bumpkin farm boys.┬á I'm ugly, shriveled and don't have a woman. I have a creepy relationship with this orphan I helped mutilate. But trust me, this is as awesome as it gets!' You are one disturbingly pathetic geezer.
EMPEROR: throws ruling the galaxy out there one more time.
Luke: Yeah, you keep on with that. It's like you're Amway or something, multi-level marketing your repression.┬á 'Oh, please! Take over in my downline!┬á I'm all powerful but need help ruling!' What have you done with the galaxy?┬á Is GDP up?┬á What about GINI index?┬á You're like the eight year old bully who steals all the balls in the neighborhood, but throws like a girl and can't bat even with the balls, in more ways than one. If this is the best the "Dark Side" has, I'm yawning.┬á Rent yourself one of those blue chicks with the head-handles and get blown. When you can accomplish just that, come back and we'll talk. From here, I see nothing worth my time.┬á You're old and need a replacement.┬á I don't need you. Go force choke your chicken.
