 * Exaggerated: After building a robot with the logic to be your friend, the robot takes it to the logical extreme and wants to kill you with love.
 * Justified: The robot is a toy built by a Japanese distribution company to befriend humans with limited programming. Compare with a Tamogotchi, AIBO, Pleo, Robosapien.
 * Inverted: The robot realizes their "friend" is actually an evil psychopath, their Morality Chip overwrites his coding for befriending him, and he kills him.
 * Subverted: The artificial "friend" is actually built by you're worst enemy.
 * Parodied / Played for laughs: A robot is built to befriend humans. However, it can not understand friendship/ takes everything to its logical extreme/ due to Fantastic Racism and always ends up terrorizing more people.
 * The person desperately wants a robot buddy tries to befriend all machines, regardless of it's inanimacy. His entourage includes a toaster, a broken record player, and a windows vista laptop.

 * Criminals take advantage of a robot's programmed loyalty and use it to commit violent acts of murder.
 * Reconstructed: The Brain Uploading robot has their human side forcefully deleted, and thusly reverts to its original coding for befriending humans.
 * The child loner is perfectly fine with living alone, and builds even more robots to keep themselves occupied.
