I disagree. Doom isn't the type of person to hand divine cosmic power to machines unless he has a secret purpose like using Victorious as bait or it's absolutely necessary like his treatment of Molecule Man.
But seriously, if Franklin is so much as surprised by Doom's eventually betrayal, he should be picked up and tossed head first out the nearest window. I get he's not a genius, but he can't possibly be that dumb.
