You want it to be one way.

i loved this part i told my brother that for weeks all the time

Marlo didn't have to terminate the security guard like that. Damn shame.

Possibly my favorite scene from the series.

'You want it one way...'.

The Guard is the one who is supposed to be in charge. He doesn't exercise his authority out of fear but still wants to have his way by reasoning with Marlo. He obviously doesn't watch the Wire.

'.....but its the other way.'

This is the hood. Marlo calls the shots. Literally. The guard has no authority.

Thats my take and I agree that its a power play.

This gave me the chills, that Marlo would kill some one for this! Terrifying!

marlo = best character in the show

"You want it to be one way"- you want everyone in the world to have the ability- free choice- to choose good over evil- for example, playing it straight and getting a legitamate job. "But its the other way"- like butchie told Omar after bunk put a guilt trip on him- everyone in this world does what they do implying there is no free choice- Therefore Marlo said, "but its the other way". That is the source of true evil, when people think they have no control over their actions.

what did he mean by You want it to be one way.

This was the only line in the show I didn't get thanks to the people like eidon513 who explained it, I don't agree 100% but I think your explanation is the best I heard
