Leslie Knope is a trash character. Off the top of my head:
She tries to fill in the pit, injures Andy, sends him to the hospital, and then manipulates him into not suing the city.
She, without Ann's knowledge or approval beforehand, she tries to auction her off for a date at the fundraiser.
She stalks out Ann and Mark under the guise of weed being planted.
She convinced Mark to then propose to Ann just to boost ratings on the telethon so people would donate more money after flat out ignoring Ann who was going to tell her she was going to break up with him.
She pushes Ron to reconnect with his ex wife who turns him into a maniac just so she can make a political move against the librarians completely ignoring how this would affect Ron.
Ron wins Woman of the Year and she can't stand losing this award and she is insufferable when trying to say he's undeserving even after it's explained to her why they chose a man for this award.
There are more, I guarantee it. She's the worst character on that show.
