I loved the finale, but it also got me thinking; Eddie shot himself causing RF to cease to exist. This means he was never able to travel back in time, never able to kill Barry's mother, and never able to cause the Particle Accellerator explosion. Thawne would have also never been able to kill the original Harrison Wells, thus making it so the Particle Accellerator would be turned on in 2020 as originally scheduled; meaning no metahumans until that time (or at all because the PA would function properly). Without his mother's death and his father's incarceration, he wouldn't have motivation to go into the police force to find his mother's killer.

Furthering this on Arrow if Barry wasn't motivated by his mother's death OR in the police force, Oliver Queen would have died from the serum that was injected into his bloodstream in season 2 without Barry's help with the rat poison... or in the very least if he survived Ollie wouldn't have anyone to help him with his R'as situation in season 3.....there are SO many things in this universe that depend on Eobard's existence and intervention in the present day timeline, that when he is removed from that equation there are so many ripples that could completely destroy the order of things, let alone the fabric of time itself......I think too much but it's an interesting question as to how this would all fit.
