He used the Blade while he was a soldier ,once he moved up he had no need for him then . This is when all the kill him came from. I never herd it out of Nick sr mouth of course.
It came from the Blade ,he always thought after he was on a load that he had done wrong and many times he had ,but Nick did not find out hardly ever.

And that stuff Nick was saying after he was boss is when he had those Mexicans around and he was shining them around his guys ,like theses are the guys that will hit you if you don't shape up. WTF they were all just kids or young men....
