Twinkie Defence? Not in Chassidus (Unit 3 Unifications Ch. 6, Ch. 10 in DM)

And the thought receives [the light/inspiration] from the emotions [desires]. It's impossible to contemplate something that is not attached to some desire...and the speech receives from thought, The light of the soul cannot be expressed in speech without first going through thought.

We see people talking and it makes an impression that there is no thinking involved. That's impossible. One who has no thought cannot speak. The level of the thought is just very low, not sophisticated and so the speech sounds the way it does. But the very fact that this person is talking means he's elevated to a level much higher than simply a parrot. 

All this is to explain is that in general the thought and speech, mind and desires are all ordered hierarchically. The soul is not thrown together wildly but rather structured in an orderly fashion. The relationship between emotions or desires and thought and speech is described in Kabbala by the metapor of the relationship between Jacob [the emotions and desires] and Leah [thought] and Rachel [speech]. There is much discussion about these two aspects and why Jacob preferred Rachel over Leah. 

Also in Tikun Chatzot, the nightly Midnight Rectification Prayers, there is a Tikun [Prayer for Rectification] of Rachel, and a Tikun of Leah. The tone for the Tikun for Rachel is sad while the tone for the Tikun of Leah is joyful.

The Tzemach Tzedek has shown that all additional energy that comes into the world has to come down in the form of some kind of unification between a higher and lower entity.  Sometimes we ask a person why they did something and they answer that there was no reason - we've shown that this is impossible. Life is a constant flow from intellect to emotions to thought and speech and eventually also to action. Every action must have its root somewhere in our minds. If we train our minds properly to exclude negativity then eventually, there will be no room for any negativity on any of the other levels.
