Well, you've already seen Gus kill a child to manipulate Jesse into getting himself killed. And if you've seen 4X1 you've seen him in action with a box cutter.
I suppose they could have taken Breaking Bad in the direction to have Walt continue on his original mission to run a drug business without being involved in the violence. It could have still turned out a good, but very different show that way.
