As much as Shinya/Evil's last moments just seems to satisfy his sense of jealousy, you've got to feel rather teary when Blade, in anguish, STOMPS the Radam bug that controlled Shinya, too late to learn that if he could find that earlier, he wouldn't need to kill Shinya/Evil. This is continued with how Blade prepares his last assault against Omega, declaring that D-Boy or Takaya Aiba is dead, only Tekkaman Blade remains... continued with Aki's ignored pleas for him to stop... even with her crying.
