In tangentially related thoughts, I just realized that Hux’s hand was forced with the defection of Finn - he had to use the weapon before the Republic evacuated the Hosnian system. I wish this was better explained in the film. If during the first Snoke scene Kylo mentioned the defection of FN-2187, it would better explain Snoke’s freakout:
Snoke: "…the new Jedi will rise."
Kylo: "And FN-2187?.."
Hux: "Supreme Leader, I take full responsibility…"
Snoke: "GENERAL! Our strategy must now change."
Hux: “The weapon is ready. The time has come to use it…”
