Killing Sutherland's character-spoilers
Why didn't JS's character:
1. Ask him if he did it?
More importantly,
2. why didn't Sutherland's character tell JS's that he didn't do that?
It was almost as if Sutehrland's character acknowledged having done it, which I found very surprising for this kind of movie, where they were old friend, and he was a decent guy- aside from being a hitman. It wasn't 'til JS's saw the guy who faked his death, and beat him for answers, that we learned the truth.
It seemed like Sutherland's character would've, or should've protested as he was inocent of that crime. He deserved to know why he was being killed, which was what, getting suspicious, snooping too much, greed?
