Continuity mistake: After Batman shoots Reverse Flash through the head, Flash rushes over to Batman and catches him before he falls over from his wounds. As Flash is lying him down slowly, there is no blood on Batman's face. It then cuts to a close up as Batman reaches up to pull off his mask and there is suddenly blood on his lips and chin.

Chosen answer: Thawne spent his whole life wanting to discover the speed force. When he did, he became The Flash of his time. But Thawne couldn't live up to Barry's legacy. It drove him mad. And drove to eliminate Barry.
