Answer:
Empathy for them, because they intend to gain something
Explanation:
Research has found an answer to the question of whether people will help out-group and in-group members. People help their in-group members because of the feeling of empathy for them and out-group members because of what they stand to gain.
Individuals in a group feel more closely knitted together and hence feel more affected by the disadvantage of any of their member, thus they are more likely to help that member because of the feelings of empathy towards him, a hurt to one is a hurt to all. On the contrary, when people help individuals they are not in the same group with, they do so with the hope of getting something in return, maybe financial benefits or any other type of benefit.
