Rick Sanchez is complicated. He's smarter than every other, uh, what's the word... human on the planet, but he spends most of his time getting riggity-riggity-wrecked and hanging out with his grandson. His past is mysterious, but we do know one thing for sure: Rick is kind of a total prick. He left his wife and children at least 14 years ago (probably longer, though), we know that he's a total pessimist, and we know that he has some serious substance abuse problems.
But while he may seem like a total a**hole, there are a few sweet moments from Rick and Morty that show that Rick Sanchez is actually a good guy. Okay, okay, Rick Sanchez being nice? That's like the Joker feeling remorse, or Superman being a dick. Strange as it may seem, these things do happen. Think about it and you'll probably come up with some instances right off the top of your head. Like that time he takes Morty to Blips and Chitz, or Tiny Rick, or that one time he totally cried.
Here are some examples of nice moments from Rick and Morty that prove that Rick Sanchez actually has a heart. Just make sure you're all caught up with the series (you are a real fan, aren't you?) - there are spoilers ahead. Because of course there are, use your brain.
Rick Sacrifices Himself For Morty
In "A Rickle In Time," the Season 2 opener, Rick shows that he's willing to make the ultimate sacrifice for Morty. After time gets split across 64 different possibilities, all 64 versions of Rick, Morty, and Summer put on their time-stabilizing collars to resynchronize time. In one of the timelines, however, Morty's collar is broken, and Rick sacrifices his own life to save Morty.
This proves that Rick is literally willing to die for Morty. He accepts his fate as he says "I'm okay with this... be good, Morty. Be better than me." Haunting yet touching (almost) last words.
Rick Finishes Morty's Dumb Adventure With Him
In the Season 1 classic "Meeseeks and Destroy," while Morty and King Jellybean are... struggling in the bathroom, Rick is playing cards with some of the townsfolk.
After Morty returns, he's understandably shaken. Rick seems to sense this, drops his gruff demeanor, and suggests that they finish Morty's adventure. After all, a good adventure needs a good ending.
Rick Turns Himself In
In the Season 2 finale "Wedding Squanchers," Rick and the Smith family leave Earth to find another home after the squanch hits the fan at Birperson's wedding. While checking out an underground cave/center of the planet, Rick overhears the others arguing - Jerry wants to turn Rick in to the authorities, but the rest of the family are willing to put up with Rick for fear of losing him.
After hearing this, in an act of selflessness, Rick turns himself in. He really does have a soft spot for his family after all.
Rick Straight Up Murders King Jellybean
In the fan favorite episode "Meeseeks and Destroy" from Season 1, Rick gets revenge on King Jellybean for trying to sexually assault Morty in the bathroom. The best part? Morty had already gone buckwild and beat the snot out of King Jellybean.
Rick really went the extra mile by murdering Jellybean. The fact that Morty didn't even see him do it shows that Rick did it out of the goodness of his heart, not to gain anything from his grandson.
