They are many reasons: 1. Some people just come from a tough background. Their family/friends experience may not be all rainbows and unicorns and they may have been treated badly.
This can greatly affect the way they act towards other people. 2. They have a big ego and pride.
Some people are really full of themselves and see other people lowly. 3. They may not know how they are acting.
Some people don't know that their mean. They are just acting like themselves and no one corrects them. The best way to take care of mean people, is not to be mean back to them.
We (as responsible mature people) have to understand their attitude and realise that there may have been bad experiences that shaped that person's thinking. If possible, let them know that they're mean and hurting people and even though they may not show it, they probably took what you said into consideration.
They were never taught humility and respect for others.
