Ramsay Bolton, the compassionate and
misunderstood Bolton bastard that always made sure that his dogs were fed. Not only did his best friend since Season 3 Reek kill his mistress and run off with his wifey Sansa but his dad was poisoned by the enemies and his step-mother died from child birth complications. Sadly the child never made it thus making Ramsay the only remaining Bolton as he lost his entire family within a single a day.
Feelsbadman, he never wanted to be the only child. Things quickly took a turn for Ramsay. He found the runaway lord of the Stark sub-clan, Rickon his brother-in-law and he went out of his way to escort him back to his elder sister with an army. The banished bastard Jon interrupted the royal escort and tried to snatch Rickon away, Ramsay tried to protect Rickon by covering him with his bow and arrow but Rickon jumped into one of the arrows there were shot.
Rest in Pepperoni, Rickon.
Fast forward a bit and Ramsay's army held a peaceful protest around the Stark militia but they weren't having it and things quickly took a bad turn, Ramsay soon enough had a ragtag alliance of barafjires and Starks along with a giant ajanabi chasing him back to his ancestral home Winterfell. Like the police brutality that we now see in the states, Ramsay was pinned down to the ground, beaten with a shield, punched to a pulp before being locked up in a cell where they eventually fed him to a Cerberus.
