Which transformers do you think would be the most likely to be able to do both good and evil things? I am talking about they can make a conscious decision to do both a good or evil thing because they can not because they have to, to save their own transistors.
Alot actuality. IDW Prowls has strongly eluded to some. Any of the wrecks i bet Most version of the dino-bots. Dinobot Double dealer Flip Sides? maybe? DO G1 Constructicons count? In one of there orgians; They started good but then went bad.
Pretty much every Transformer besides some of the Autobot medics and builders and maybe Beachcomber as well.
