Rick is a character from the popular television series The Walking Dead. In the show, Rick is a sheriff's deputy who is forced to take on a leadership role when the world is overrun by zombies. While Rick is generally a competent leader, he has made some questionable decisions over the course of the show.
One of these decisions occurred in the episode Better Angels, where Rick decided to kill a fellow survivor named Randall without giving him a fair trial. This decision led to backlash from some of Rick's friends and allies, and ultimately resulted in Randall's death.
However, it seems that Rick may have finally gone too far in the season 7 episode The Other Side. In this episode, Rick kills two unarmed men who were trying to surrender to him. This act was witnessed by several people, including Michonne and Maggie.
As a result of his actions, Michonne decides to leave Rick and take Maggie with her. It's possible that this will be the beginning of the end for Rick Grimes.
