Actually, considering everything else he's done, this could be considered tame for Eobard Thawne.
This is a man who killed the love of Barry Allen's life, tried to murder his second love, then went further back in time to kill the first one again earlier in the timeline. He also shook his other obsession so hard, he retroactively made her an invalid. All while doing incredibly petty shit like pushing Barry down the stairs as a child.
