Savitar emerged as a side effect of Barry's Flashpoint correction. I guess it can be argued Eobard's subtle change to post-Flashpoint played a part in it, but ultimately it was still Barry's fault for creating Flashpoint to begin with.

Eobard didn't stop his ancestor from killing himself at all, he was still a time remnant. That's the thing with Eobard, even killed and erased from existence, one careless time travel event and he'll be back.
