Now just to warn you now, I just started the 5th season, so there will be spoilers, but please no spoilers for me in the comments.
First of all, after having left his best friend in an alley to be raped by his bullies, Amir spends the rest of his life trying to redeem himself. Feeling very guilty for many years, Amir is finally able to redeem himself when he saves Hassan's only son, Sohrab, from the Taliban, and brings him back to live with him and his wife in America.
Comparatively, in season two of Breaking Bad, Jesse meets a girl, Jane Margolis, and they eventually start dating. Unfortunately, Jane was a recovering heroin addict, and because of Jesse's meth addiction, she started using again, and eventually overdosed and died. Because of this, Jesse was filled with enormous guilt as he felt it was his fault she died, as he could've prevented her from using again, and avoided her death. In season three of the show, Jesse meets another girl, Andrea Cantillo, at Narcotics Anonymous. He's finally able to redeem himself when he stops Andrea from turning back to drugs, to protect her six-year old son Brock, and by providing her with enough money to live a nice life, and allowing the two to live with him. Jesse is finally able to redeem himself since Jane's death.
Both Amir and Jesse have gone through rough times, and have let their loved ones get hurt, but they both strive to redeem themselves, as they don't want to live with the overwhelming guilt anymore. Because of their good hearts, they are able to get rid of the guilt, by preforming a good deed, and both characters are able to live happy lives in the end.
