"Walking Dead" fans are enjoying the gut-wrenching episodes developing week after week. And Sunday's episode, "Killer Within," could have been one of the most appalling episodes of all. Here is what LATimes had to say about the episode:

“In the episode, two major characters, who had both been with the show since the beginning, met their untimely ends. T-Dog (IronE Singleton) and Lori (Sarah Wayne Callies) shuffled off the "Walking Dead" cast list, though not together.

While T-Dog ended things the old-fashioned way (i.e. he got torn apart by a pack of ravenous zombies), Lori's end was crueler, more heartbreaking and, in the end, more powerful. After giving birth to her baby via crude c-section, she died from blood loss and her young son, Carl, had to put a bullet into her body to prevent her from coming back as a zombie. Intense, right?

The one-two punch of loss coming this early in the season (it was only the fourth episode of Season 3) caught many viewers off-guard. Most of the time, major losses are reserved for the end of the season.”

Florida Gators center Patric Young tweeted, "The Walking Dead last night was indescribable. If you ddnt tear up even a little you're not human."

Former "Seinfeld" star Jason Alexander exclaimed on Twitter, writing, "OMFG The Walking Dead tonite!!!!! OMFG. Literally took my breath away. This show is insane. I am in complete shock. Wow."

"The Middle" star Patricia Heaton expressed similar sentiment writing, "I hate when I cry over fictional characters! #WalkingDead."

On the other hand, not all shared the same empathy towards Lori. Her passing away became an open door for fans to reveal how much they actually held the character with much disdain.

Hungarian fan Eniko Balazs wrote from Budapest, "I always hated the character of Lori. But this. That bloody drama. This was the best @WalkingDead AMC episode. WOW."

San Diego video gamer "Morpheus Himself" wrote, "Kinda happy to see Lori die in this last episode of Walking Dead. She was beginning to annoy me haha."

Keep on watching to see what other surprising events are lurking around the corner!
