Bender is often mean and disrespectful in regards to other people's feelings. At one point, he flushed Leela's beloved pet Nibbler down the toilet, and didn't feel bad about it until the Professor attached an empathy chip to his head, forcing him to feel other people's emotions. He is also quite arrogant, frequently bragging about how great he is. Bender has no emotion about committing crimes and often steals people's wallets or items from shops. He loves smoking and drinking, though as a robot he has to drink alcohol to keep him going.
