A Hate Sink is a character in a work of fiction that has been deliberately written to be so irredeemably vile and unlikeable that the audience wants said character to fail.
Saki's Mother in the game Yakuza 3 is a total Hate Sink; they didn't even bother to give her a name in case it made her relatable in any way.

A person you hate intensely not because they deserve such hatred but because they serve as a focus for your general hatred. A healthy way to dispense with excess animosity.
