Here's how it came across to me:

Burai: Was misguided, then possessed the Sword of Hellfriede which messed with his mind and made him unstable causing him to turn to Bandora's side. However he managed to fight through the madness and destroyed the Sword in the process. So he wasn't evil... just misguided and being influenced by the sword. Could be held partially responsible for his actions.

Tsukumaro: Was good, but then put on the mask which completely possessed him and turned him evil. When it was destroyed, he reverted to his old good self. Could not be held responsible for his actions.

Mikoto: Was a Doctor who craved excitement, and upon getting his powers CHOSE to fight against the heroes... not to conquer Earth but just for the sheer thrill of it. It was only when he realised the villains were using him that he decided to join the Abarangers. Maybe he wasn't evil, but he was totally responsible for his actions.

Utchy: During the Sengoku period, Dogold's armour encased itself around Utchy's body to use him as a host. Utchy was literally trapped inside Dogold for the first part of Kyoryuger... could absolutely be in no way held responsible for what Dogold did.
