Honestly, there isn't much meaning to the splendid names given to you by your parents. What does have meaning, is what the person behind that name does during their actual lifetime.

Wake up to reality! Nothing ever goes as planned in this world. The longer you live, the more you realize that in this reality only pain, suffering and futility exist.

The selfish desire of wanting to maintain peace causes wars, and hatred is born to protect love. 
-Madara Uchiha (Naruto)
