Does Near want to use the death note for himself? Tsugumi Ohba, writer of Death Note, said that Near "becomes less likeable" as the story advances, citing Near's plan to take the notebook at a later point in the story. Ohba said that a negative reaction originated from "the difference in their attitudes" and that people may have viewed Near as "a cheat." Ohba added that Near's "cheeky behavior," intended to "reinforce his childishness," had been construed as "annoying." 

I don't know what this quote from Ohba means. Does this mean Near wants to use the Death Note for himself? Can someone please explain this to me?
There's nothing that I have read or watched in DN that indicates to me that Near is interested in using the power of the book for himself; he is interested in capturing a mass-murderer!

Oba-sensei was discussing the character's childish nature, but being cheeky, ill-mannered, underhanded and generally pugnacious does not mean that he wants to kill people using supernatural agencies!
