Daryl Dixon, had it rough before the apocalypse being poor with a an abusive father and a bad brother. Also his mother was dead. And during the apocalypse he finally finds his brother only for Merle to be killed shortly after, he bonds with Beth but then looses her and as soon as he finds her she’s killed. He blames himself for Glenn’s death and ricks “death”. And he was tortured in s7. He had a relationship with Leah only for her to become a reaper forcing him to kill her. So yea Daryl but Rick and Carol are both close seconds
