All stories need a villain, an antagonist. This piece from the British Psychological Society tells you how to create yours.

one of the core traits a villain should show is a low “welfare trade-off” ratio: they are free-riders who cheat and steal, taking from their community while contributing nothing. Such behaviour is undesirable for societies today, but it would have been even more of a disaster in prehistory when the group’s very survival depended on everyone pulling their weight.
