A Person's Character

"The best index to a person's character is how he [or she] treats people who can't do him  [or her] any good, and how he [or she] treats people who can't fight back." -  Abigail Van Buren

Spot on Abigail. It's easy to be kind to someone who is kind to you. Virtually everyone can do that. Thus, it is important to see how a person treats those who cannot benefit him or her, and those who can't fight back against him or her.
