Moe Szyslak (seasons 16-30)

Moe Szyslak is a character from the long-running American animade sitcom The Simpsons. He has been badly butchered during the most recent seasons.

Why He Sucks

 * 1) He became the show's punching bag. Even before he was the show's punching bag, he was the main punching bag whenever he gets prank called by Bart.
 * 2) Moe started out as a simple bartender who was kind of cheap and surly, but was a generally okay person to be around. Sure, he watered down the beer and encouraged his regulars to stay longer than they needed to, but he was okay. Now he's a registered sex offender. He revolts women and smuggles animals and he actively encourages alcoholism, even as he knows it's destroying his regulars. He's rarely seen doing anything that's not illegal or unethical.
 * 3) He also makes regular attempts at suicide that are foiled not by anybody persuading him otherwise, but by coincidence - that's right, the show plays it in a way that suggests Moe's inability to kill himself is bad luck.
