The Walking Dead: 10 Best Antagonists
10. Inmates
Not long after arriving at the prison, the group discovered they weren't alone when they came across a band of prisoners who had spent the outbreak locked inside the cafeteria. And while two of them later ingratiated themselves with Rick and the gang, the inmates' de facto leader, Tomas, wasted no time in making them all look bad by attempting to kill Rick.
For his effort, Rick buried a machete in the inmate's skull, ending his little rebellion before it could take off. In response, Tomas' buddy Andrew bolted, only to find himself outside in the midst of a group of walkers, where he was locked out and left to die by Rick.
Unfortunately, Rick's failure to see Andrew's death through came back around, as he survived, lured walkers into the prison, and stirred up the chaos that led to T-Dog and Lori's deaths, his actions tainting the group's new safe haven and forever changing the group - especially Rick - going forward.
