The artist of this picture probably wants us to see that there are always two sides to the story. There is the typically happy unicorn, and the rabid unicorn, the dark side. There is always two views on a situation, and you need to be aware of this. Not everything is what it seems and we can see that by these two very different unicorns. The white unicorn represents the good in people and the rabid unicorn represents the bad. People are generally good, but you always has to look out for the bad.
