YMMV / Little Children

  • Jerkass Woobie: Larry Hedges. A cop who got fired after he mistakenly shot a kid at the local mall, his life ever since has become a downward spiral. Having lost his job and suffering from PTSD, he doesn't find a new one, instead taking up vigilantism against local sex offender Ronald. His wife gets exasperated by that, which causes him to lash out at her and she leaves him. He latches on to Brad and includes him in his team as a protege, only to be overshadowed by the charismatic Brad. At the end, Larry gets frustrated by what he perceives to be Brad and everyone else's embarrassment of him, and harasses Ronnie again, causing his mother's death by a heart attack.
