The purposes of punishment include rehabilitation, as you mention, but also deterrence, incapacitation, retribution, denunciation, and restoration:
Deterrence: Destruction of the corporation serves as a lesson to the rest of society, to scare them away from doing the same.
Incapacitation: A corporation which no longer exists cannot reoffend.
Retribution: The deserve nothing less.
Denunciation: Overlaps with deterrence; gives people the benifit of knowing they live in a society where wrongdoing is punished. Suppresses vigilantism.
Restoration: The funds retrieved by bankrupting and liquidating the corporation can, at least in principle, go towards undoing the harm the corporation caused.
As for stealing candy bars, I think there is merit to going light on children. But corporations? Corporations are not children. They aren't even people. They deserve no mercy.
