Yes.
Its harder for many people to be kind, some find it easier to be cruel or indifferent. But thats cos its habit, if you get in the habit of practising kindness, you get better at it.
Another interesting thing about kindness, is that God created animals after their own kind, meaning they were the same as each other, they belonged to the same family. Even though on the surface we have our differences, which is great because we are diverse people, underneath it all we are basically the same. Our blood is the same...its red, and when we cut ourselves, we all bleed.
