Does Barry not realize the reason why things are so bad in the future is because he became such a selfish person the moment he got together with Iris? He literally becomes less of himself around her and shuts off everyone else. Iris clearly brought out the worst in him. Even Savitar said he’s the real villain.

Killer Frost of the future pointed this out when she said in 3x19 “there’s no hate in your eyes…yet.” Savitar has to be Barry of the future. Look at all the clues that add up!
