Bourne and Jarda
First, I really love the Bourne movies especially Supremacy. The only problem is every time I watch this part; I still can’t understand why Bourne would do this.
Bourne goes to Jarda’s house to see what information he can gather. Jarda doesn’t tell him anything relevant, only that Conklin is dead, and that treadstone is shutdown. Before interacting with Jarda, Bourne has Jarda tie his hands. Later on, the phone rings and a fight break out between the two. Bourne ends up killing the man. Why?
Couldn’t Bourne have left him incapacitated? Even if Jarda told the CIA team that showed up, Bourne was here, and they circulated a photo of him to the police, Bourne showed many times he could evade them. He disables one of the before entering a cab.
If you wanted to kill, why not the man that killed your girlfriend? After an intense chase through a tunnel, you confront him, but leave him. You could have killed Abbott but he does that to himself later.
