Can someone offer a different perspective or do you agree?

Ok so this is a random thought that just popped in my head. It’s likely to change if someone can convince me that I am wrong for thinking this and why.

Ok so what if I told you that there is no such thing as mental uniqueness or mental individuality. That everything you are is based off the influence of someone else. Your views, your emotional responses, and your goals all conditioned. You are influenced to believe in a specific religion or to not believe. You are influenced to decide what’s right from wrong. Nothing is your own thought or belief. The only true individuals I can think of are the humans that are raised by non-humans (wolves or apes) and were completely secluded from human society. We view those kids as “wild” but think about all of the thoughts that run through their heads are uninfluenced. It’s all them. You can argue that the animals who raised them influenced their thoughts but I would disagree that even though the humans were raised by a different animal that still have human brains that probably still think differently. Am I right or is this a total blasphemous thought?
