How about Misunderstanding who is at fault? That explosion was going to take place on the ground and kill a lot of people. It only happened in the air next to the building because Scarlett Witch was trying to move it. Misunderstanding who is to blame for the explosion leads to people being mad at the Avengers for helping and the passing of the accords.
Gathering Mis-Information about who set the bomb leads to Bucky being framed.

Zemo Obtaining revenge means the team will be split up.
