Tywin Lannister from A Song of Ice and Fire.
SPOILERS
He was the beloved and competent King's Hand for the mad king Aerys for 20-odd years and his people are safe and prosperous.
But he's obsessed with his house getting respect. To that end, he'll sack a city and have his especially brutish henchmen kill women and children to be on the winning side, he'll unleash said brutish henchmen on the lands of a noblewoman's birth family for arresting/kidnapping his youngest and least-favored son, he'll use sick, sexualized punishments on (allegedly) gold-digging women (the forced nude parade of his father's mistress and the rape of Tysha), he'll mastermind one of the worst acts of treachery in a continent's history (the Red Wedding), use his children as pawns, etc.
And yet when he dreams his children (well, two of them) will be brave and strong and beautiful and nobody will ever laugh at them, I can empathize.
