I refuse to believe 8th Brother is dead.

I personally believe 8th Brother is still alive, for 2 reasons. 1: He's a Terrelian Jango Jumper, much like Cassie Cryer in Clone Wars. Their a species known for great acrobatics and large leaps, so a high fall shouldn't be as lethal to him. 2: In the Episode, Dual of the Droids, we saw Ashoka and Anakin jump out of a ship onto the Listening Post, without parachutes. I refuse to believe 8th Brother couldn't also stick the landing.
