The battle was over, crit or not. My Milotic had Toxic, my Sceptile could have KOed all of your remaining pokemon himself with proper switches, Rhyperior would beat Altaria and Hitmontop, and severly crippled Milotic on a switch-in, and Scyther would put Milotic into KO range or revenged.
Using a suicide lead has its risks, this was an instance of the consequences.
