Rick Grimes

"You still don't get it. None of you do! We know what needs to be done and we do it. We're the ones who live. You, you just sit and plan and hesitate. You pretend like you know when you don't. You wish things weren't what they are. Well you want to live? You want this place to stay standing? Your way of doing things is done. Things don't get better because you want them to. Starting right now, we have to live in the real world. We have to control who lives here. (...) Me? Me? You-- you mean me? Your way is gonna destroy this place. It's gonna get people killed. It's already gotten people killed. I'm not gonna stand by and let it happen. If you don't fight, you die."

- Rick to Deanna Monroe and the Alexandria residents.

Rick Grimes is the main protagonist villain of The Walking Dead, although not always evil, and he loves his family, he eventually let the stresses of the zombie outbreak get to him, and his methods are very questionable. He also becomes more ruthless and violent as the series goes on.

Appearance
Rick is a fairly tall Caucasian man with a slim figure, and although his age is unspecified, he appears to be around his mid to late 30's. He has dark brown wavy hair, and through the first three seasons keeps facial stubble and eventually a small beard. His apparel and clothing changes throughout the seasons, but is most notably identified with his beige and brown police uniform, along with his brown US Cavalry/Sheriff's hat (which is later given to his son, Carl). He also keeps his brown police holster, which carries his favorite side-arm, his classic Colt Python .357 Magnum.

Personality
Rick was in the beginning calm, smart, and a good friend and father, but he would always cling to a strong personal moral code, which has resulted in many bad decisions and deaths. Rick's greatest fault, is his ability to place responsibility on himself and set for himself goals that are impossible to reach. This has deteriorated Rick's relations Lori and Shane, and often weighs heavily on his mental state. Despite his faults, his combat skill and general care for all members of the group have led him to be looked up to, and allowed him to take the leadership role within the group.

However after season 3 when Lori dies he's very mentally unstable and starts falling into more evil territory, now having no problem in murdering humans, even though it is to keep the people safe, it seems he let go of the moral code, and this results in a number of deaths/attempted murders including: later in the show we see Rick having a vengeful mentality, trying to murder a bunch of survivors who threatened his friends despite the effect this might have on other people and killing them all for supplies and this lands Rick in a bad situation where he meets Negan, this bad decision on Rick's part ends in multiple deaths at the hands of the saviors.
