Not surprising, you never really seam to grasp context. It's why you lose so many arguments (albiet in your mind you never lose, you almost always lose in the court of public opinion).
1) when Jamie made the statement in WF, it was in regards to the things they had previously brought up (so this excludes pushing Bran out the window you dolt). What precisely was he accused of? Killing the Mad King (justified) Killing many Northerners (they were at war, justified), Fighting Ned Stark in KL (somewhat justified, the North was holding Tyrion prisoner at the time). Leave it to you to once again try to twist what he said into something it wasn't meant to be. Epic fail #1
2) When he convinced Edmore that he would kill everyone in riverun to get back to Cersei, he actually saved the lives of many. Your insistence that he would have actually carried out the threat is nothing but pure speculation on your part. Epic fail number #2
3) he left Cersei, he fulfilled his promise. He fought for the better good of humanity, against Cersei's wish's. As to what his true intentions are in heading back to KL is still an unknown, yet your treating what he told Brienne as fact.
If his intent is to kill Cersei, convince her to surrender, etc in an effort to prevent more bloodshed and save more lives, then you have lost the argument. You are quick to forget it is just not Cersei who's life is at stake, but Jamies unborn child. As to whether or not you agree to this is of no consequence to me, but the court of public opinion will be on my side, and epic fail number #3 will be in place.
3 strikes and your out
