Humans are emotional creatures and make life or death decisions based on them. It’s a flawed system, but it has worked adequately so far. For example, taking care of the people in your tribe boils down to emotions. This sort of cohesion keeps the tribe together and safe, so I would consider that a successful survival mechanisim.
