EMOTIONS

Robots have taken over the world. Only some survivors. If a human is found they have two options:
Become a Robot
or
Die.
Now, most bots are mostly created from being captured but there are super advanced, very strong, very intelligent robots made from scratch. Pure metal and wires. Their main duty is to work, capture, kill.
But what happens when a one of the most advanced robot goes out and realizes there's more to the world than capturing and killing.
Maybe even find a love....in a human.
But How?
Robots don't have EMOTIONS.
