Any good TV show has to be built around a strong cast of characters. They have to be relatable, and need to give us a reason to root for them, to invest and actually care what happens to them. With a few exceptions, usually these characters are fundamentally good, but that doesn't mean they can't do bad, sometimes horrible things.
Where most cartoon shows are based around a typical yet dysfunctional American family, Futurama is based around a work family. Fry, Leela, Bender, Amy, Hermes, Zoidberg, and the Professor make up Planet Express, and with the exception of one alcoholic robot, they are all generally good people.
Yet, just like any other characters, they have their moments of weakness. Whether it's shooting down a friend's romantic advances in the harshest way possible, letting a woman get between them, or accidentally causing the murder of billions of baby aliens, the Planet Express crew are far from perfect.
Through eight seasons, four movies, and over 100 episodes, of course these seven characters have done bad things, however some are far worse than others, and some are very close to irredeemable.
