Explanation:

 Agreeableness

People who exhibit high agreeableness will show signs of trust, altruism, kindness, and affection. Highly agreeable people tend to have high prosocial behaviours which means that they’re more inclined to be helping other people. 

Sharing, comforting and cooperating are traits that lend themselves to highly agreeable personality types. Empathy towards others is commonly understood as another form of agreeableness even if the term doesn’t quite fit. 

The opposite to agreeableness is disagreeableness but it manifests in behaviour traits that are socially unpleasant. Manipulation and nastiness towards others, a lack of caring or sympathy, a lack of taking interest in others and their problems are all quite common.
