Ethereum won't die because of this, it will correct itself and potentially another fork is under-way. Now, i'm not expert when it comes to the base of Ethereum's code, so correct me if i'm wrong.

But from a market perspective, this along with segwit's cancellation is adding to Bitcoin's value, but it will not last long. Ethereum may dissipate a bit on the markets, but i suspect a big rebound is incoming sooon, since it has a lot of catching up to Bitcoin's huge valuation at this point.
