Lil Kevin didn't even work for Marlo.
Avon wasn't killing people over trivial shyt. He mad fukkups in his crew after season 1 too.
Kevin was told to speak to Lex, whether he's a contractor or employee, he didn't follow orders.
Someone already made mention to Avon killing the witnesses and killing the prison inmates. Avon isn't less of a sociopath, he just grew up in a different time and with a separate set of rules. They are both sociopaths. Arguing which is more ruthless is like figuring out which Army generals were more ruthless. Body counts and tactics scale with time, but the idea of a person willingly making the decision to kill and harm for their own gain, does not.
The key here is when Cutty says, "the game has changed," to which Slim Charles responds, "naw, it just got more fierce." Difference between a leader and a soldier is the ability to recognize, adapt to, and exploit this.
Game is the game...always. Marlo isn't anymore ruthless than Barksdale, he just grew up in his own time. He's willing to resort to non-traditional tactics (using girls like Snoop and young kids such as the asthmatic dude) in order to achieve victory. Barksdale and Bell likely had to do the same when they were coming up, just in a different way.
Capitalism is ingenuity, talent, hard work bearing great fortune. It's also a lot of folks left behind.
shyt is a treatise on capitalism and warfare.
