16) His emotional breakdown after Merle's death

In Season 3 of The Walking Dead, Daryl is devasted on seeing his brother Merle turn into a walker. It emotionally breaks him down as the last of his blood relatives — his older brother — is dead now. In a heartbreaking display of love and mercy, Daryl puts walker Merle down, an act that takes a tremendous emotional toll on him. He then collapses in tears, allowing himself to grieve openly for the first time.
