lol I got Kenny's bro speech in my (almost) asshole Lee save. I couldn't be a complete asshole, it was harder than I thought
I didn't save Duck or Shawn...I just stood there

I told Kenny to kick Larry's ass
I didn't give anyone an energy bar (I don't know if that's important)
I gave Duck and Kenny food
I helped kill Larry
I took food from the car
I sided with Kenny on getting out of the motor inn
I left Lilly on the side of the road
I beat some sense into Kenny
I killed Duck
I told Christa that we had to keep moving
I killed the boy in the attic
I voted to leave Ben behind
I dropped Ben
I think those are all the choices that matter because they have something to do with Kenny in some way. Honestly I think a large part of getting the bro speech from Kenny is whether you kill Larry and/or Ben.
