Yup, newspeak is designed to change people thoughts and how they act making them vulnerable to certain influences and ideologies. We think in language, so when we are constantly barraged with propaganda meant to change the definition of words or create new words to replace the old, then we think the way they want us to think and act they we we are socially engineered to act. Peer pressure and newspeak play a large role in the left-wing insanity that is dragging everyone into the abyss. The world which would come of the left-wing gaining total ideological victory would be a nightmare and lead to man made horrors beyond our comprehension (Which is already happening a fair bit right now but has the potential to be far, far worse)
I'd recommend you read 'Brave New World' after reading '1984' to get an even better understanding of what this newspeak is meant to turn the world into.
