That raises a disturbing possibility
What if he's a sloppy sentimental "happy" drunk?
Can you imagine him at a Bush White House reunion, crooning out sentimental favorites like "All the Boys We Tortured There" and "All We are Saying, Is Give War a Chance", or jolly at the office Christmas Party, "All I Want by Christmas Is Just Two More Wars". Bet he tears up a little when he pulls out the old scrapbook of snapshots from Abu Gharaib, and slugs back another belt of whiskey remembering the glory days. Gazes fondly at the diploma listing top honors as a graduate of Sith University, with honors in necromancy, and smiles proudly to think how well he's served the Dark Side of the Force in his long and malignant career.
I'm not sure I wouldn't rather deal with a mean drunk.
